» Modernization of Oil-Submersible Cable for Electrical Submersible Centrifugal Pump – Outfitting Non-Metal Armor

One of the main reasons for the rejection of the oil-submersible cable during its repair is the corrosion of the armor. The steel armor of oil-submersible cable contacts directly with the corrosive aggressive well fluid and gas during the wells exploitation in the Volga – Ural region, complicated by the hydrogen sulfide. That process eventually leads to the formation of corrosion defects. The process of shedding of corroded parts of the steel armor of the cable starts during the lifting of the oil submersible cable from the well and, as a result, the reduction of the protection from the mechanical damage of the insulating layer of the conductor cores of the cable during tripping operations starts too. One of the possible solutions may be the use of corrosion-resistant steels as the armor. However, the use of the expensive materials will increase the cost of the oil-submersible cable in general, that will inevitably effect the growth of the specific cumulative oil production costs by a mechanized method. Taking into account the latest achievements in the field of production and application of polymer materials, the unmetallized general polymeric armor should be used as one of the possible ways to reduce the rejection of oil-submersible cable during its repair. This technical solution allows to improve technical characteristics of the cable to increase its reliability, the corrosion resistance, to simplify the design and to reduce the weight of the cable. The usage of polymeric materials instead of steel will also reduce the overall cost of the oil-submersible cable (as an optimization of capital investments) and will reduce operating costs taking into account a decrease of mass of 1 running meter. The article describes the results of the first experience of using the cable with unmetallized general polymeric armor at the deposits of Samaraneftegaz JSC.

Keywords: electrical submersible centrifugal pump, oil equipment, polymer, metal-sheathed cable, rejection of cable, down-the-hole corrosion (hydrogen-sulfide corrosion), oil-submersible cable of new century.

» The Improving of the Energy Efficiency of Cyclonic Devices for Emissions Cleaning in the Industry by Natural and Numerical Explorations

The main goal of the work is the development of the cyclone filtering devices, which are applied in existing cleaning facilities. The prototype of the cyclone filter apparatus was created and tested. In the result of the research the level of particles deposition with different physical parameters was identified with the prototype of the cyclone filter apparatus. The theoretical expressions for the estimation of the efficiency of the particle deposition in a vortex flow were obtained using the Navier – Stokes equations of motion for flow and the first Newton's law for particles. Levels of particles deposition in the cyclone depending on the Reynolds number were determined. The calculations of the dependence of critical Reynolds numbers Rer were performed. These numbers are relevant to the separation of the particles from the flow, rotating in the annular section of the cyclone model with a flow rate at the entrance u0 = (1…7) m/s and radii of curvature 0.065; 0.085 and 0,1m. The numerical studies of the air flow movement based on the prototype of the cyclone were performed too. Levels of particles deposition in the cyclone depending on the Reynolds number were determined. The changes of tangential velocity and the static pressure at several cross-sections of the cyclone were detected using the methods of computational hydrodynamics. This development will allow to increase the capacity of cleaning facilities by four times with the improvement of the quality of gas purification, which is expressed in the reducing of the size of the captured particles at 50 % (the cut-off diameter) from the average values for the cyclones of 5–10 µm up to 0.4 µm. The noticed improvement in the quality of cleaning does not require the additional energy consumption that is one of the advantages of the device over analogues.

Keywords: a cyclone, a filter, a separation, a degree of purification, a method of modeling.

» Analysis of Dynamics of Oil and Water Production from Khadum Deposits of The North-Caucasian Oil and Gas Province by Wave Dynamics of Fluid Mode

The paper considers the possible interrelation between the expansion and subsequent compression of the Earth (pulsations) and the dynamics of fluid extraction from zones subject to tectonic stress is considered in the article. In 1933, V. Bucher named the phenomenon of expansion and contraction of the Earth by pulsations and suggested that in the phase of Earth's expansion, the Earth's crust was stretched and geosynclines formed, and the compression phases within their boundaries there were folds. This hypothesis was developed in his studies by M.A. Usov and V.A. Obruchev. The absence of reliable proofs of the phases of a general global expansion (or contraction) is the most significant flaw in the hypothesis. Separate phases do not always occur simultaneously on the Earth at the same time. Stretching is most clearly manifested in the mid-oceanic ridge. Compression - manifests itself in the folded belts of the Earth, where the horizontal crushing of rocks and squeezing them up and in the sides, and due to the increase in temperature (from the friction of compression), there are processes of metamorphism, magmatism (granitization), crushing. The paper gives brief information about geological, geophysical, lithological and seismic information in the area of research. The histograms of liquid extraction rates have been constructed for some of the existing deposits in the region that have been producing since the 1970s. The connections between the wave course of the dynamics of the fluid regime and the rates of fluid extraction are established. The alternating stages of the oilfield work are distinguished, the wave course of fluid regime dynamics of oil and gas deposits is traced, and therefore, a relatively new pulsational scientific theory of compression and expansion of the Earth's interior is possible.

Keywords: Khaduma Formation, hydrocarbons appraisal of resources, production forecast, structural geology, fracture analysis, dispersal movements, accumulation of hydrocarbons, dynamics of hydracarbons selection.

» The Determination of the Longitudinal Stability of CPS Bolsters Using Cleaning and Diagnostic Tools

The specialists operating these facilities faced with a lot of issues since beginning to use the bolsters of the internal protection of a welded joint on pipelines with an anticorrosive covering. There were such issues as the determination of the longitudinal stability of the bolsters using various cleaning and diagnostic tools (CDT). The perfect answer on the question: «What kind of CDT is it possible to use on the pipeline with installed bolsters?» must be given by the producers of bolsters and CDT. In practice, the operators empirically determine the possibility of using CDT on pipelines with installed bushings of the internal protection of a welded joint. CDT producers have distanced from this issue now. Producers of bushes have to give some recommendations at their own risk, based on the feedback from consumers of products and their opinion. That sometimes leads to such excesses as a breakdown of installed bolsters by a shell or, conversely, stopping of a shell in the bolster. To determine the criteria for the selection and application of any SDT is enough to designate the force exerted by the shell on the bolster installed in the pipeline and to compare it with the force of breakdown of a bolster, in other words to compare with its longitudinal stability. Determining the longitudinal stability of the bolster is usually not difficult and is realized on any hydraulic press with force control. It just remains to determine the force of an action on the bolster by a shell passing through it to settle the issue. The authors of the article carried out tests, the purpose of which was to determine the longitudinal stability of CSP bolsters during the passage of devices of various design – cuffed, foam «bullets,» polyurethane balls DN 100, 150 and 200 mm. The tests were carried out on a control sample, which consists of two welded coils with an installed bolster on the weld joint. The shell was entered in a sample by temporarily welded junctions and directional coils. The pushing of the shell was performed using a set of various rigs. According to the test results, a conclusion was made about the effectiveness of applying of this method of determining the longitudinal stability of bolsters. The obtained data make it possible to recommend the usage of cuff and foam cleaning devices for pipelines with covering and installed CPS bolsters. The separate tests are required to formulate recommendations for the usage of CDT of another design.

Keywords: a stock of longitudinal stability, bolsters of internal protection of welded joint, cleaning and diagnostic tools, cuff pistons, polyurethane balls.

» Stand Development for the Simulation of the Mechanical Modeling of Deformation Processes of Threaded Connections of Tubing in Aggressive Environments

It is shown that the production of oil and gas as well as workover tubing exposed to the destructive effects of hydrogen sulfide environments, reducing the basic mechanical characteristics of metal tubing. Integrated action processes multiple deformation threaded surfaces of the pin and box tubing during tripping operations and aggressive environments in their local contact zone contribute to the accelerated destruction of the equipment. This destructive effect requires monitoring during the operation as well as research methods and evaluation methods of increasing the efficiency of tubing during the deformation of corrosion-mechanical nature. Analysis of test benches designs available today for conducting comprehensive research of deformation processes of threaded connections of oilfield pipes in aggressive environments has shown that these mechanisms are very metal content. In most cases, studies are conducted under real production conditions at the wells, and require significant production costs to carry out works. The article reviews the main operational factors affecting the performance of threaded connections of tubing in oil and gas wells. For a reasonable simulation of the basic parameters for accelerated life tests in aggressive environments made their assessment on the magnitude and nature of the action. This article also presents the main design elements of the proposed technical solutions to practically implement the patented mechanism for current divergent studies of the performance of tubing in multiple screwing and unscrewing in hydrogen sulfide environments. The features and characteristics of the material elements are the parameters of of test samples of tubing.

Keywords: stand, mechanical modeling, screwing and unscrewing, tubing, threaded connection, deformation, wear, hydrogen sulfide environment.

» The Optimization of Ejector Systems for the Gas Industry

Supersonic gas ejectors are used in various industries. In the oil and gas industry, they are successfully used for the utilization of low-pressure gases in integrated gas treatment plants, as well as for creating a vacuum in oil refining facilities. However, in the process of using ejectors, enterprises are faced with the problem of low efficiency of the process of mixing gases in the chambers of mixing ejector systems. The emergence of the so-called critical operation mode, in which a current flow reaches the speed of sound in a stream of low-pressure gas, significantly limits the characteristics of the ejector. The search for an optimal scheme for supplying of the high-pressure gas to the mixing chamber of the ejector acquires special significance. The part of the high-pressure gas passes through the longitudinal slits and mixes with the low-pressure gas in an ejector with a perforated nozzle mounted on a supersonic nozzle. Then this stream is ejected by the main supersonic stream leaving the nozzle. The paper shows that the use of a perforated nozzle increases the compression level in comparison with the classical optimal scheme. The comparison of the results of the calculation of the multi-structure design and the classical optimal scheme shows that the use of a distributed gas supply increases the maximum compression level. The replacing the central supersonic nozzle of the classical scheme with seven supersonic nozzles also increases the maximum compression level. The recommendations for the choice of geometric parameters of ejector systems, in which the nozzles are located on the surface of the mixing chamber are shown and given in the paper. It is shown that such schemes of mixing different pressure streams have a maximum compression level among the all schemes shown in this paper and significantly exceed the compression level of the classical optimal ejector.

Keywords: an ejector, a sound of speed, the increasing of the efficiency, the stabilization of a condensate, the gas industry, a compression level, a high pressure.

» Combining Thermal Insulation of Pipeline and Refrigerating Machines in Transport of Hydrocarbons in The Northern Regions

The problem of selecting the minimum thickness of thermal insulation for an underground pipeline is considered. It is shown that the minimum thickness of heat insulation is substantially dependent on the seasonal climatic conditions and the temperature of the transported liquid hydrocarbon. At the same temperature of the hydrocarbon, the necessary thickness of thermal insulation should be determined on the basis of spring conditions, which will lead to inefficient use of insulation in the winter. To reduce the consumption of thermal insulation, it is necessary to additionally use the cooling system of the transported liquid hydrocarbon. The condensate cooling system should effectively work more than 6 months a year. When underground pipelines are used to cool condensate in the northern regions, it is better to use propane-butane steam-compression refrigerating machines. Condensate cooling is technologically necessary and economically feasible for condensate pipelines constructed in conditions of the Far North in areas with permafrost soils. A combination of a condensate cooling system and the use of thermal insulation are possible.

Keywords: underground pipeline, thermal insulation, the temperature, condensate, soil, cooling system.

» Analytical Presentation Viscosity-Temperature Characteristics of Diesel Fuels Brands EURO According to GOST R 52368-2005 During Pipeline Hydraulic Calculations

In the article examined questions of the analytical presentation viscosity-temperature characteristics of diesel fuels brands EURO in accordance with GOST R 52368-2005 during hydraulic calculations of pipeline transport oil products. The first part of the article contains overview of the most common formulas for determining the Darcy friction factor. Was shown that when calculating the Darcy friction factor in Darcy-Weisbach equation, practically for all flow regimes and conduits of hydraulic friction, with the exception of the so-called Turbulent flow in Rough-pipe conduits the correctly choice of the values of the kinematic viscosity parameter included in the Reynolds number is essential when Fluid flow through pipelines. Finding the Darcy friction factor is necessary for calculating the friction loss pressure, as well as determining the flow rate. Was also carried out analysis of common formulas for the analytical presentation of viscosity-temperature characteristics of oil products. In the second part of the paper, part of the article contains the results of a Research viscosity-temperature characteristics of diesel fuels in accordance with GOST R 52368-2005 type III (with total sulfur content not more than 10 mg/kg), EURO grades Class 4, Class 3, Class 2 and Sort C, produced currently time by different oil Refineries. The values of the main physico-chemical and operational parameters of the diesel fuel samples studied are presented, as well as the results of studies on the change in the kinematic viscosity values as a function of temperature. As a result of the processing of the experimental data of the of the test samples, analytical dependencies are obtained that allow to determine the kinematic viscosity values of diesel fuels EURO according to GOST R 52368-2005 at a fixed temperature. The results of calculations of the kinematic viscosity based on the proposed dependences are compared, as well as using the Valter-ASTM and Reynolds-Filonov formulas with experimental data. The proposed dependences are in good agreement with the experimental data of the investigated samples and can be recommended for use in conducting hydraulic calculations of pipelines.

Keywords: diesel fuels, kinematic viscosity of oil products, hydraulic calculation, Darcy friction factor, Walter-ASTM formula, Reynolds-Filonov formula.

» The Selection of Polyacrylamides of Various Compositions to Increase the Oil Recovery Using the Polymer Flooding Technology in the Conditions of High-Temperature Reservoirs and Blanket Waters with a High Salt Content

Polymer flooding – a physico-chemical method of enhanced oil recovery when, the viscosity of the injected liquid is increased to reduce the ratio of mobility between oil and water and increase the oil recovery factor (ORF) by adding synthetic water-soluble polyacrylamides. A polymer concentration from 500 to 3000 ppm is typically used in polymer flooding, which provides an additional increase of the ORF from 5 to 15 %. Despite the fact, that the polymer flooding was recognized as an effective method of enhanced oil recovery of mature objects, new tasks posed by the interested partners nowadays are include optimizing total costs and reducing risks, associated with the implementation of physico-chemical methods of improving the oil recovery of blankets. This practice is most effective in conditions of high reservoir temperatures (above 85 °C) using the injected saline with an increased salt content. It is necessary to use special stable polymers with monomer additives to ensure stability in the blanket in such conditions. These polymers containing acrylamide-tert-butyl sulfonate (ATBS) and N-vinylpyrrolidone (NVP) are more expensive than usual polymers, and their dosage should be increased to provide the required viscosity, because their molecular weight is lower. However, in many deposits there is an access to soft saline solutions of injection containing a total dissolved salts less than 3000 ppm. The usage of such salt solution is a major advantage for polymer flooding because less durable polymers can be chosen, and the required viscosity can be achieved with smaller doses. The selection of polymers for high-temperature conditions of the formation (from 85 to 140 °C) using saline solution of various mineralization is justified in the work. A series of rheological tests and tests for determining the shear and thermal stability were performed to select the most suitable polymer in each case. The influence of chemical composition and microstructure shows that the introduction of NVP is not always necessary to ensure stability for six months at temperatures above 100 °C using a solution of a low salt content. The results also show that ATP improves shear and thermal stability in both soft and hard salt solutions. In addition, the injection of heat-resistant components in the polymer increases the viscosity, which leads to a reduction in the dosage of the used reagent, even at a high temperature, to achieve the required viscosity. The research goal is also to demonstrate the possibility of developing innovative and cost-effective polymers for specific blanket conditions. This implies a close collaboration between the polymer manufacturer and the company.

Keywords: the polymer flooding, a polyacrylamide, monomer additives, ATBS, NVP, a high temperature, a high salt content, the physico-chemical method of enhanced oil recovery of blankets, oil recovery.

» The Influence of Concentration of Abrasive Particles in the Produced Fluid to the Reliability of Electric Centrifugal Submersible Pumps

One of the main reasons for the failure of electric centrifugal pumps (ESP) installations in the operation of oil deposits with terrigenous catcher is an abrasive and erosive wear of the working steps and clogging the flow channels of impellers sand. Based on the statistical data of the failures of equipment operating 6768 wells in the fields of Western and Eastern Siberia with a terrigenous catcher, the dependence of reliability of ESP operation was constructed with floating-type wheels of a two-bearing structure made of non-resist material of the type 1 with intermediate bearings mounted on the shaft at 0.5 m from the concentration of abrasive particles in the produced liquid. Using the obtained dependences, many practical problems can be solved. For example, such problems, as an estimate of mean time between ESP failures, with increasing or decreasing the concentration of abrasive particles, the prediction of mean time for new deposits, making an informed decision about the optimal level of equipment durability, as well as decisions on the reasonability of using sand-shielding devices, etc.

Keywords: reliability of the ESP system, operation the ESP system in the complicated conditions, ESP protection from the sand, increasing of the mean time between ESP failures.

» The Question Of Parametric Series Of Equipments Of Electric Submersible Centrifugal Pumps

For the Russian oil industry installation of electric submersible centrifugal pumps (ESP) are the main equipment for lift formation fluids to the surface of the Earth. Due to the constant changing conditions of exploitation of oil fields of engineering and machine-building firms create new types of ESP; only in the last 6-8 years created and given to the oil companies more sizes ESP, than was created in all previous years. For example, in a database of soft «Autotechnology» there are more than 2200 types of pumps (ESPs), 1390 more types of submersible motors (SEM), more than 250 types of gas separators and gas dispersers. A number of options of equipment that can be used for oil extraction, leads to a twofold result: on the one hand, almost for each well can be found the best option of equipment to maximize the efficiency of oil production from this particular well; on the other hand, a large number of sizes of equipment leads to unnecessary costs for the manufacture, testing, storage, maintenance, repair etc. of the equipment. In this regard, and in connection with the widespread use of variable speed drives for SEM technologies and cyclic operation or conditional-constant operation (CCO) of the wells again became a topical issue on the ESP standard series. The article presents the scientific background for the creation of parametric series of pumps ESP on the main parameter is the flow in the nominal mode, given information about the current parametric number of pumps ESP and its features. Shown tendencies to change the number of sizes of ESPs with regard to the use of variable speed drives and technology conditionally-constant operation of the wells, the updated parametric range of the main parameter of the downhole centrifugal pumps – flow in the nominal mode when the of speed rotation of the rotor of the pump 2910 r/min. The use of this number will significantly reduce the cost not only manufacturers of this type of equipment, but also the costs of the service companies and oil companies. All this will lead to a significant reduction in total cost of ownership the main type of oil production equipment – electric centrifugal pumps.

Keywords: unit of electric submersible centrifugal pump, parametric number, number of standard sizes, variable speed drive, total cost of ownership.

» System Analysis of Operation Parameters for Main Pipeline Maintenance Equipment

The analysis of the modern condition and structure of equipment for main pipeline linear part maintenance revealed that its renewal rate is very low – 1.5–2.0 % annually, while the previous norm of 8–12 % was rather efficient. This fact significantly decreases equipment performance parameters and increases operating expenses. This paper provides the structure of information and calculation support for construction engineering in complex climate and environmental conditions in order to improve efficiency of materials and equipment for construction works at linear objects. The paper considers options of construction resource efficiency; it offers methodology to collect equipment parts for overhaul of linear sections of main pipelines taking into account different conditions of certainty and uncertainty using automated control systems.

Keywords: main pipeline maintenance, automated control systems, resource engineering, equipment population.
