» Modern Technologies of Obtaining Polyethylene for its Use on External Coatings of Main Gas and Oil Pipelines

The article reviews the technologies of obtaining polyethylene which is used as an external layer of the anti-corrosion three-layer coating for metal steel pipes. There is an active introduction of domestic polyethylene brands taking place in the territory of the Russian Federation as part of the import substitution, and in light of this the task of improving the quality of polyethylene-based coatings has become especially topical. As of today the most widespread coating is a three-layer polyethylene coating which is due to its high quality and climatic peculiarities. The requirements to polyethylene and polyethylene-based coatings are regulated by GOST R 51164-98, GOST R 52568-2006, and by industry-specific regulatory documents which enlist such requirements to polyethylene-based coatings as processability on high-speed coating lines, structural, frost-proof, heat-proof and thermal-resistant properties, cracking resistance, anti-puncture resistance and ripping resistance. You can obtain a high-quality material by co-polymerization of ethylene with -olefins and by making a composition consisting of high-density polyethylene (HDP) and various modifiers of its properties. The article analyzes the Russian market of insulating polyethylene brands, their properties and production technologies. The domestic polyethylene brand РЕ6146КМ, which is manufactured with the use of the technology of obtaining bimodal polyethylene by gas-phase polymerization of ethylene with -olefins, is described in detail. If necessary, РЕ6146КМ polyethylene can be modified at the stage of extrusion/compounding.

» Experience of Usage of Electrolyteless Dry Electrodes of Comparison for Long Autonomous Operation on Pipelines (DEC-2EChemD)

The article presents the substantiation of the requirements for long-lasting reference electrodes based on the analysis of errors in the method of an auxiliary electrode shutoff, as well as the feasibility of solving this task including the use of DEC-2EChemD electrodes (TU 3435-001-85247759-2012) with a potential of 1000±10mV over a chlorine-silver electrode. The principle of the electrode operation is based on the use of a micro-galvanic DC source and a potential corrector for its calibration as a potential-determining system. According to the calculations and the pilot operation, the calibration allows maintaining the declared accuracy of ±10 mV during the entire service life of 30–40 years with its periodicity of 5–10 years. Based on pilot operation data, the deviation of the potential of DEC-2EChemD electrodes without a corrector did not exceed ±2 mV in two years in the pipeline section with a low level of stray current and salt content from ±4 to ±15 mV in the section with their high level on individual reference measuring instruments. The perspectives of using DEC-2EChemD electrodes as a portable reference electrode, in which the required increased accuracy of ±3 mV is achieved by a simple calibration of the chlorine-silver electrode, are considered. The standardization of long-lasting reference electrodes for accuracy and application is also discussed in the article. Namely, copper-sulphate electrodes with an error of 50 mV can be used in pipelines without any restrictions. However, more accurate «other types» of electrodes with an error of ±10 mV are allowed to be used only «in remote corrosion monitoring systems». The authors conclude that it is necessary to revise some regulatory industry documents in the field of import substitution and the introduction of high-quality innovative products.

Keywords: pipeline corrosion, electrochemical protection, cathodic polarization, protective potentials, measurement errors, reference electrode, auxiliary electrode.

» Approaches to the technical state assessment of dynamically loaded equipment of hazardous production facilities

Modern approaches to the problem of technical state assessment of dynamically loaded equipment of hazardous production facilities are considered in the article. It presents the technology of technical state assessment and industrial safety ensuring of industrial equipment in such industries as refinery, chemistry and petrochemistry, petroleum and gas mining. The technology is based on the results of computational and experimental assessment of the technical state of hazardous production facilities equipment that belongs to the hazard class I or II in accordance with the results of noncontinuous/continuous monitoring of control parameters. Taking into consideration the results of the preliminary examination of the plant equipment it is offered to divide the dynamically loaded equipment into two groups of criticality. For each group it is suggested to use different strategies for equipment state examination during the operation and different amount of implemented tools that improve the dynamic ability. It is suggested to use the strategy of continuous equipment state monitoring with simultaneous implementation of passive and semiactive tools for managing the dynamic state of the equipment of the group I. The strategy of noncontinuous monitoring is suggested for the equipment of the group II. This technology allows to detect the parameters of dynamic impact for the examined equipment that were unknown during the design stage. It also allows to assess actual loading for these facilities correctly and develop and implement the preventive measures for improving the dynamic ability to ensure industrial safety on hazardous production facilities and to mitigate the risks of emergencies. The article shows the results of the use of the suggested approaches in respect to the equipment of the criticality group I with the help of example of the crude vacuum unit-6 (ELOU+AVT-6) used by Angarsk Petrochemical Company JSC.

Keywords: hazardous production facility, technical state assessment, computational and experimental methods of investigation, vibration-based diagnostics, technical diagnostics, technical state monitoring.

» About Senoman High-Viscosity Oil Deposits Developing

The first pilot development of senoman deposits with high-viscosity oil in West Siberia detected main problems and showed complexity of the process. Uncontrolled gas and water breakthroughs to oil production wells (both vertical and horizontal), abrupt decline of oil rate during the first year of oil production (because of some geological and technological reasons) are among of these problems. A significant difference in high-viscosity oil, gas and water mobilities within a single hydrodynamically bound reservoir system, as well as the closeness of oil well perforation intervals to gas-oil and water-oil contacts are among of these factors. Reduction of one of the negative factors, for example, gas breakthroughs in oil wells with high-acive aquifer water, will allow to prolong the period of acceptable technological regime’s work. Some scientists consider, that simultaneous production of oil and gas or the advancing gas production at the initial stage of development are possible ways of production optimization for reduction of the influence of the upper gas on production oil wells work indexes. However, advancing gas production can lead to the movement of the oil rim into the gas-saturated part of the deposit, above the gas-oil contact. So we built hypothetical model of high-viscosity oil deposit with gas cap, which is maximum approximate to real geological model of some field. With the help of the model we show, how prime gas cap production influences on high-viscosity oil rim disbanding. Also we analyzed different geological factors sensitivity analysis showed, that vertical connectivity of a reservoir has the greatest impact on oil migration to gas cap.

Keywords: high-viscosity oil, oil rim, gas cap, gas production, oil production rate, oil flow, gas-oil contact, reservoir pressure, oil saturation.

» Study of Interfacial Tension at the Boundary between Hydrocarbon Phase and Acid Compositions based on Sulfamic Acid and Surfactants

Currently, one of the main methods for the restoration and improvement of permeability of the bottomhole well zone is the acid treatment method, however, its efficiency is constantly decreasing. A significant influence on the success of the acid treatments is the introduction of surfactants into the acid composition, which reduces the interfacial tension and prevents the formation of persistent oil-acid emulsions and precipitates upon contact of the acid composition with the formation oil. The article presents the results of studying the interfacial tension at the boundary of the acid composition-kerosene and acid composition-oil, depending on the type and concentration of surfactant, acid concentration. The example of acid compositions based on sulfamic acid (SAA) shows that the use of kerosene as a model hydrocarbon phase doesn’t always give comparable results compared with the use of oil, does not take into account the interaction of surfactants introduced into the formulation of acid composition with native surfactants of oil. Along with this, the work presents the results of an evaluation of the ability of the surfactant-acid compositions to destroy oil-acid emulsions upon contact with the Romashkinskoye oil field. On the basis of the comparison of the interfacial activity and the demulsifying ability of the surfactants studied, the absence of a direct dependence of the parameters under consideration on the type of surfactant was shown, which indicates the impossibility of developing an individual surfactant of universal action and the need for a laboratory evaluation in each case. Among the surfactants studied for the conditions of the Romashkinskoye deposit, the addition of the anionic surfactant Neftenol VVD to acid compositions based on the SAA was recommended.

» Non-Organic Materials Adsorption of Lignosulphonates Obtained in a Number of Different Ways

One of the most complex physicochemical processes in drilling of wells is adsorptive interactions at the interface of rocks. In the construction and operation of oil and gas wells, the latter may be formation water, oil, process fluid or its filtrate. Quantitative characteristics of the effectiveness of these processes are quantities such as work of adsorption, dimensions of adsorbent molecules, the capacity of the adsorption layer, the thickness of the protective membrane formed at the interface. The aim of the work was to carry out comparative studies of the adsorption properties of lignosulfonates used in drilling technology. In this work the influence of the methods of obtaining lignosulfonates on the adsorption losses associated with the decrease in the concentration of the solution during adsorption on rock models, such as clay and quartz sand, was studied. It has been established that lignosulphonates can be obtained through neutral-sulphite method. Lignosulphonates reduces the surface tension of solutions and has significantly lower adsorption losses, in comparison with sulphite lignosulfonates, which has smaller area and length of molecules, that practically excludes the phenomenon of chemisorption and does not contribute to the formation of strong sorption membrain of «rock formation – drilling mud». The calculations carried out also showed that the adsorption work for neutral sulphite lignosulfonate is ten times lignosulphonate sulphite, which practically excludes electrostatic interactions at the interface, preventing the formation of an adsorption layer associated with the surface of rocks. This is reflected in a decrease in the efficiency of drilling reagents based on neutral-sulphite lignosulfonate, thereby reducing the rock drillability and the stabilization parameters of disperse systems of drilling muds both for washing and plugging purposes.

Keywords: lignosulphonates, rocks, the work of adsorption, the adsorption film of the solid phase.

» Impact upon the Running Time of Electrically Driven Centrifugal Feed Pump Units and the Pump’s Rotation Speed in the Course of Operation of Wells which are Complicated by a Mechanical Impurity Outflow

One of the complicating factors that reduce the time between installations of electric submersible centrifugal pumps (ESP) to failure are the mechanical impurities contained in the produced products. These failures are caused by two factors: clogging mechanical impurities, and wear and tear items of pumping equipment. In ESP installations there are three basic types of wear: radial wear; the wear of the axial bearing surfaces; hydroabrasive wear. The wear of the working bodies of the pump is significantly affected by the characterization of the mechanical impurities: particle size; particle shape; percentage of sand; the index of aggressiveness of the sand. These indicators are determinants of ability to use a particular ESP design for efficient operation in the well. Currently permitted content of mechanical impurities not bound to such important indicator, as the pump flow. For modern mechanical ESP the number of abrasive particles passing through the pump during the period of its operation depends on supply and can change hundreds of times. For high capacity pumps number of mechanical impurities, passing through the pump per year of operation, can reach 500–600 tons. Another important parameter that influences the operating time of pumps, is the shaft speed of the pump. Calculations show that by increasing frequency from 50 to 70 Hz, the time to failure caused by wear of the working bodies of the pump is reduced to 2.74 times. The accounting value of the aggressiveness of the abrasive particles, the pump capacity and rotational speed of the pump shaft will optimize the design and improve the efficiency of ESP installations.

Keywords: installation of electrically driven centrifugal pumps, wear, mechanical impurities, the index of aggressiveness, frequency of rotation, a pump capacity.

» The Reuse of Pipes on the Facilities of the Gazprom PJSC: Reasonableness, Expediency and Effectiveness

The article studies the issues of the capabilities to reuse pipelines after a long-term exploitation on the pipeline gas transportation facilities.

The analysis of complex experimental researches on pipes with a various operational term was carried out. The analysis was carried out in order to identify changes of the physical and mechanical characteristics and residual life of both domestic and imported pipes with diameter from 325 to 1420 mm. The analysis was carried out for pipes that were made of steels of different grades and have different strength characteristics. Pipes for the experiments were selected from the emergency stock as well as from the routes of various main gas pipelines.

It was noted that in 2010 Krasnodargazstroy JSC managed to create a pipe replacement fund in order to use pipes on the facilities that are under construction as well as to supply the pipes to these facilities. The common price base for re-use pipes was determined. The base was not exceeding 40 percent of a cost of a new pipe. A modern polyurethane insulating coating was developed. This coating can be applied in factory and route conditions as well as on technological pipelines. The line for repair and insulation of pipes in Lyamino Village (Perm Region) was launched. There is also an active preparation for the creation of a base on the Gazprom transgaz Saint-Petersburg enterprise. A set of equipment for repair in road conditions was created.

The conclusions about the reasonableness and expediency of the re-use pipes were made. And the conclusion about the effectiveness of the re-use pipes was made. The reuse of pipes does not change the performance parameters of the facilities of the Gazprom PJSC.

Keywords: the pipeline, the reuse of pipes, overhaul.

» Analysis of Pilot Hydrofrac, Acid Hydrofrac and Large-Volume Bottomhole Treatments in Mendymskian Domanikites and Sargaevskian Domanikoids

Share of tight oil is rapidly growing in the worldwide petroleum production. Hydrocarbon-bearing formations in Russia similar to shale reservoirs are the Bazhenov Formation in the Western Siberian basin, Domanic reservoirs in the Volga-Urals Petroleum Province, and the Khadum Formation in the Pre-Caucasian region. Tight oil reserves development and elaboration of technologies to enhance production of non-conventional hydrocarbon reserves facilitate energy market growth. PJSC TATNEFT has approved a pilot program on search for tight oil reserves and their development. In the period from 2013 to 2015, studies and testing were concentrated on the Mendymskian domanikites where pilot hydrofrac and acid frac treatments were carried out. Based on shale volume, all reservoir beds in the treated wells can be divided into two groups: low-shale-volume and high-shale-volume reservoirs. The results of field trials in the Mendymskian domanikites underline the need for further comprehensive research and improvement of pilot projects with regard to the lessons learned. In-depth study of rock mechanics is a key to improvement of hydrofrac efficiency and success rate in tight reservoirs. Conventional minifrac treatments in tight oil formations provide little, if any information. Long fracture closure time prevents determining parameters for redesign; so, alternative methods have to be used, such as injection/flowback testing, pulse method, or hydraulic impedance analysis. PJSC TATNEFT’s business units involved in the Mendymskian domanikites testing should use and adjust technologies which have proven successful for tight reservoir development.

Keywords: tight oil, hydrofrac, minifrac analysis, Mendymskian domanikites, tight reservoirs.

» Evaluation of the Possibility of Application of Plast Pressure Support Systems at the Deposit of Eastern Cheleken

Based on the study of geological features, lithological structure and the analysis of the development of the deposits of the Vostochny Cheleken deposit, an assessment was made of the possibility of using reservoir pressure maintenance systems (PAP) in order to extract the residual hydrocarbon reserves in the most complete way. The main factors influencing the possibility of the application of the PAP systems are geological, technological and mineralogical. Geological factors are due to the high heterogeneity of the productive strata, complex tectonic conditions, and low reservoir properties. Moreover, at present there is no unambiguous interpretation of the fault-block structure of the field. There are risks of spreading undetected faults in productive deposits of the deposit. To solve this problem, the authors propose to use the method of analysis of the curvature of structural surfaces, which will reflect the mechanical curvatures of the structure, most often associated with unloading tectonic stresses. The need for non-standard equipment in connection with large depths of productive deposits is related to technological ones. The intervals of occurrence of the red-colored strata within the deposit range from 3000 to 4500 m, the creation of the necessary injection pressure at a given depth is impossible without solving a number of technological problems. Lithological factors, a poor knowledge of the mineral composition of clays and, as a consequence, the risks of the content of montmorillonite clays swelling in water. The investigations carried out on this deposit are limited to 2 wells (for which the core was selected), and secondly they are not conditional because they can not give an unambiguous answer about the content of minerals of the smectite group. On the basis of a comprehensive study of these factors, the authors made a decision on the impossibility of applying a PAP system to this deposit.

Keywords: Eastern Cheleken, reservoir pressure maintenance, faults, tectonic disturbances, filtration-capacitive properties, clay minerals, montmorillonite, borehole, core, mineralization.
