» Six-roller drilling bit with big diameter with carbide preparation for reactive turbine-unit drilling

The features of multi-roller drilling bit with big diameter kinematics in conditions of reactive turbine-unit drilling are considered. Kinematics of the drilling bit rolling cutters with enlarged diameter is analyzed while it is rotating around its own axis, operating without slipping of gear equipment on the bottom hole. The factors that affect the magnitude and direction of slipping of gear equipment on the bottom hole in conditions of the reactive turbine-unit drilling are determined. Disadvantages of the multi-roller drilling bit equipment geometry designed for solid drilling, when used in reactive aggregates turbine drilling. The study undertaken in this article allowed making the conclusion that the production of drill bits with enlarged diameter, using sections from the standard body bits for continuous drilling is not rational, since the geometry of usual bits equipment does not consider the interaction of the equipment gear with bottomhole surface in conditions of the reactive turbine-unit drilling. Based on the survey conducted the scheme of six-roller drilling bit for the reactive turbine-unit drilling, equipped with hard-alloy gear equipment of new design was developed. The main feature of this structure is the presence of specially oriented multidirectional hard-alloy gear equipment, allowing not only increase the area of the bottomhole coverage, but also increase the intensity of its destruction. Application of the offered bit equipped with multidirectional hard-alloyed gear equipment of new design will allow improving the efficiency of well drilling with method of the reactive turbine-unit drilling by increasing the destructive capacity of equipping and reducing the energy capacity of rock fracture process that eventually will enable raising drilling rate and mechanical speed and reducing the cost of bores and wells of enlarged diameter with method of the reactive turbine-unit drilling.

Keywords: reactive turbine-unit drilling, cutter drilling bit, instantaneous rotation axis, gear equipment, hard-alloy gear.

» Prospects of new technologies in oil and gas well cementing

In the paper, the ways of solving issues such as the regulation of the rheological parameters of cement slurry during oil and gas well cementing, an improvement of quality of the hardened cement stone, providing a durability, with the application of advanced technologies, including nanotechnologies, are considered. It is known that for adjusting rheological parameters of cement slurry depending on the well depth and thermobaric characteristics, various reagents are added. Nowadays, to improve the rheological parameters of cement slurry and the quality of cement stone, formed after the hydration process, a large number of chemical additives is produced by various companies. In laboratory studies there were used the products manufactured in Russia and Italy. These chemical additives are mainly composed of hydrophobizing ingredients, superplasticizers and nanomodifiers formed as a result of synthesis of petrochemicals and wastes. From laboratory experiments it is clear that along with the regulation of the rheological parameters (fluidity, dynamic shear stress, the beginning and the end of thickening), superplasticizers and nanomodifiers added to the cement slurry also provide the solution's ability to adhesion and promote the formation of a hydrophobic surface in the cement stone. The addition of these reagents improves the strength properties of the obtained cement stone during bending and compression and reduces porosity and permeability to the minimum. Bentonite, which is used as a structure-forming agent, provides the plasticity of the cement stone and volumetric expansion of the cement slurry. In the paper there are also given test results of the chosen composition under conditions adapted to the borehole mode using consistometer КЦ-3.

Keywords: cementing, hydrophobizator, superplasticizer, modifier, adhesion, aggressive oilfield waters, metal nanoparticles.

» Effectiveness analysis of WAG considering the saturation pressure in the conditions of the Upper Jurassic deposits

This article is devoted to assessing the impact of the ratio of the saturation pressure and reservoir pressure on the use of WAG as a tertiary EOR for the Upper Jurassic reservoir conditions of Western Siberia. For the simulation of WAG reservoir simulator used Tempest 7.0. Since the majority of fields in Western Siberia is at the stage of declining production, the use of such technologies as Alternate water injection and associated gas can substantially increase the ultimate recovery factor. Experiments on real WAG fields are not always successful, which is due to several reasons, one of which is the lack of consideration of the ratio of the saturation pressure and reservoir at the time of WAG. The paper considers two types of pattern formation system. According to the first reservoir saturation pressure is less, so the reservoir system is undersaturated dissolved gas, hence the formation is in this state, when the injection of associated gas, it will be dissolved in the oil under specified conditions thermobaric. In a second embodiment of the collector it is saturated with gas at a pressure equal to the saturation of the reservoir. All the calculation results characterize the central element. The analysis found that the effectiveness of WAG has significant influence formation of the initial state. For saturated gas reservoirs application WAG may be ineffective due to rapid breakthroughs gas. At the same time for the collectors with low saturation pressure, which include most of the Upper Jurassic strata of Surgut and Nizhnevartovsk arches characterized undersaturated reservoir system, WAG can be seen as a promising method for enhanced oil recovery.

Keywords: WAG, hydrodynamic simulation, saturation pressure, saturated gas reservoir, undersaturated gas reservoir

» Numerical modeling optimizes water shutoff treatments in horizontal wells

The geological model represents a typical Bashkirian reservoir. The horizontal lengths of production and service well are 324 m and 375 m, correspondingly. The horizontal production well is placed at the top part of the reservoir, while the service well is at the water-oil zone. Based on the existing geological model a numerical fluid-flow model has been created which is a three-dimensional grid model in which each grid block is defined by a set of identifiers and geological model parameters and further contains dynamic characteristics of in-situ processes. Numerical simulations have been performed on the assumption that tracer (water-shutoff agent) injection results in 0.1 to 1-fold changes in relative permeabilities depending on tracer concentrations. This is attributable to liquid phase mobility alteration. If no tracer is present in the grid blocks, it does not affect liquid phase mobility. Should a grid block be filled with tracer, particularly in the vicinity of service well, then liquid phase mobility decreases 10 times. This paper provides the results of numerical experiments on tracer distribution in-situ. Three cases have been simulated: 1) perforations around the horizontal well section, the tracer flows to the production well covering small reservoir volume; 2) water shutoff treatment in the upper part of the horizontal section, this simulation case exhibits greater reservoir coverage efficiency compared to the first case; 3) water shutoff treatment in the upper and lateral parts of the horizontal section, the tracer (water shutoff agent) covers much larger reservoir volume than in the former two cases. Numerical analysis of WOR (Water/Oil Ratio) versus tracer injection rate has shown the appropriate tracer injection rates to be in the range of 0.5–1.0 m3/day. The numerical study also revealed the necessity to consider reservoir fracturing in numerical simulations.

Keywords: geological model, oil saturation, horizontal well, fluid-flow model, water shutoff agent, reservoir fracturing, tracer injection.

» The analysis of safety of pipeline systems on sites with connecting details

The pipeline system of oil and gas industry is a technical construction especially important for the national economics. Pipelines for transferring oil, oil products, and gas span for hundreds of thousands kilometers, they are constructed in all natural and climatic conditions, near settlements, industrial and agricultural enterprises. Oil and gas pipelines are generally laid subsurface. Faults and damages of pipelines lead to large economic and environmental losses. In this regard, the special attention is focused on their durability and safety. A complex of loadings, which form the stress-strain condition of the operated underground pipeline, influences pipelines. The level of stress-strain condition is most significantly influenced by the pressure inside the pipe cavity, temperature difference in metal of pipes (difference of temperatures during operation and construction), forces of interaction of the pipeline with soil and pipeline weight with the pumped-over product. Locations of installation of connecting details (bent branches, tees, etc.) experiencing identical loadings and influences have increased mechanical tension in comparison with, for example, straight sections. One of the effective ways to avoid damages of pipelines is improving the methods of durability calculation and development of the relevant technical solutions providing reliable operation of pipeline systems.

Keywords: safety of pipeline systems, safety factor, risk of accident, the underground pipeline, axial force in the pipeline, movements of the pipeline, tension in metal of pipes, bent branch, tee

» Analysis of the supporting elements defects of gas pumping units of the main gas pipeline compressor station

Currently, at the main gas pipelines compressor stations there is urgent problem of the fault-free operation of pressure equipment – the gas pumping units. One of the most important assembly units in gas compressor unit (GCU), using both converted aircraft engines and motors as drive, are bearing rolling and sliding elements. Today many of them are quite complex and accurate devices. The prevailing parameter of the support unit’s satisfactory operation is minimum parts wear and absence or minimum presence of defects that, if occurred, may be caused by the corrosion processes and phenomena of fatigue, and poor-quality lubricant and improper support elements installation. The document considers the main rolling bearings failure – abrasive wear of the rolling elements and roller ways, contact fatigue in the bearing rings, uneven wear caused by improper installation, increased wear due to oil starvation, separation destruction, as well as the reasons that may cause the occurrence and development of the data about the malfunctions. The most common defects of sliding bearings are also considered – destruction of the pad surface, fatigue babbitt damages, cavitation wear, appearance of tempering colors in the friction zone, babbit alloy removal of bearing, damages caused by shaft misalignment and imbalance, ingress of foreign particles between the pad and bearing bed, damage of the thrust bearings and the possible causes of these problems. It is offered to define the defects with modern methods of non-destructive testing.

Keywords: compressor unit, gas-compressor unit, rolling bearing, sliding bearing, defect, malfunction wear, contact fatigue, oil starvation, fatigue phenomena, nondestructive testing.

» Diagnosing of extended spatially deformed sections of gas pipelines in the technical state and the integrity management system of Gazprom PJSC

As a result of long-term work on the reliability and safety of the gas transportation system operation improvement for Gazprom PJSC a methodical approach for the technical state and integrity management of the linear part of main gas pipelines (MGP) was implemented that provides long-term planning of maintenance, diagnosis and repair. Planning is carried out on the basis of information about the actual technical state of sections of MGP route, obtained as a result of pig inspection (PI), and this is a priority tool for diagnosis and serves as the main strategy for management decision-making to ensure safe operation and effective maintenance of the MGP system. The main criterion for planning the for sections shutdown for overhaul as a result of PI is an integrated technical state indicator, when used in operating areas under the engineering-geological conditions of categories I and II of complexity, where the technical state of the pipeline is caused by the extent of his wall damage, allows approximation of the reliability indicators and technical state of MGP to the target values, specified in Gazprom PJSC up to 2020. Implementation of order procedure for shutdown for overhaul on the criterion of the integrated technical state indicator did not reduce the amount of numerous areas with significant deformations and spatial movements in MGP used under engineering and geological conditions of category III of complexity in addition to damages to the pipelines walls. This is due to the fact that the procedure of the calculation of technical state integrated indicator does not include estimates of the parameters and changes forecasting in the spatial position of the MGP section and the related change process of its stress-strain state (SSS) during the operation. The authors have developed a method that allows assessing the technical state and forecast MGP sections in integrated manner: both by damage criteria of the pipe wall, and by the spatial position variation.

» Integrated approach in formulating drilling-mud composition for drilling composite geologic intervals

The article is concerned with the integrated approach in formulating drilling-mud composition for penetrating pay horizons. A highly-effective formulated drilling-mud composition should not only involve the major drilling mud properties, but also minimize the penetration impact on the pay horizons while drilling. To evaluate the real impact of drilling mud (fluid) on pay horizons, it is effective co-investigate the technological parameters with the filtration and acidizing analyses. This, in its turn, could indicate the impact level of drilling mud on the pay horizon itself. This paper presents the research results in today's applied drilling-mud composition, as well as the up-dated drilling-mud composition formulated and developed in the Testing & Research Laboratory «Drilling Fluids and Cement Slurry», Institute of Natural Resources, National Research Tomsk Polytechnic University. The application of oil-base and biopolymer-carbonate drilling mud was proposed in order to minimize the negative wall packing effect. In this case, the effective drilling mud rheological characteristics including required density could be produced. This fact excludes the possible addition of bentonite-structured former which negatively affects the reservoir properties of the pay horizon in the bottomhole zone while drilling. The application of biopolymer-carbonate drilling mud, i.e. thermal resistant differently particle-sized polymers and calcium carbonates, improves the penetration efficiency through agrillaceous layers, as well as reduces the probability of problem incidents caused by swelling. It should be noted that applying different fractional composite calcium carbonates does not only result in qualitative wall packing producing a filter cake (FC) on the well walls, but also furthers the possible acidizing in order to improve the initial reservoir properties.

Keywords: drilling mud, rheological characteristics, density, thermal resistant, wall packing, permeability.

» New developments of domestic tubular goods with high performance properties

The article describes the technical issues for the construction and operation of wells in oil and gas condensate fields on the Yamal Peninsula in the spread icy and permafrost soils conditions. The substantiation is provided for the need to develop domestic casing and tubing pipes with enhanced reliability, security and efficiency for the construction of wells in the unprecedented complex permafrost conditions. The current experience of gas fields development in the Far North areas shows that the possible failures in the wells operation are associated with brittle fracture of pipes at low temperatures, casing pipes collapse in the reverse freezing of formed around wells defrosting halos, between casing pressure caused by gas backflow due to lack of tightness in the threaded joints of casing pipes. Due to the fact that the domestic industry did not develop the production of pipes with cold-resistant performance and gas proof screw threaded joints, casing and tubing pipes of a foreign production were purchased for the most demanding facilities of Gazprom PJSC, operating in the northern regions. This article describes the experience of such products production development within the framework of scientific and technical cooperation program of Gazprom PJSC and TMK PJSC.

» About reliance on analysis of hydrocarbon’s behavior for improvement of the acidizing effectiveness

Acid treatment (acidizing) is the most commonly used method of oil production stimulation today. Hydrochloric acid is widely used for acid treatments, but its efficiency decreases from year to year. Formation of asphaltic sludge during hydrochloric acid treatments is considered the serious problem. According to laboratory analysis, mixing hydrochloric acid with crude oil results in stable emulsions, moreover, viscosity of these emulsions is much higher than that of base crude oil. This can cause deterioration of filtration activity. When acid concentration and temperature increase the sludge appears with emulsion. The presence of ferric ion dissolved in hydrochloric acid exponentially increases asphaltene precipitation, which can result in colmatation. Asphaltenes exist in crude oil as dispersed colloidal particles, which are stabilized by adsorbed resins and paraffins. These stabilized micelles are disrupted by acid because of protonation mechanism. Neutralization of asphaltenes and resins by protons leads to that asphaltenes form large aggregates precipitated. Neutralization or change of asphaltene’s charge is the main reason of precipitation. Besides, there is another way of precipitation - electrophilic addition of HCl to multiple bonds in non-aromatic cyclic or heterocyclic compounds, which are found in complex asphaltene’s structures. After that ferric ion can interact with chlorine atoms from several asphaltene molecules, «stitches» them that results in asphaltene precipitation. In this paper we have tried to collect various contemporary ideas on changing crude oil compound during long period of water flood, features of hydrocarbon’s filtration in bottom hole layer as well as influence of heavy compound of crude (asphalts, resins and paraffins compounds) on the efficiency of well’s acid treatments during hydrochloric acid contact.
