The use of special designs of the stages of an electrically-driven vane pump unit (EVP) allows producing formation fluid without using upstream devices in case of a high content of free gas at the pump intake. The main distinguishing feature of the centrifugal-vortex stages from the stages of other designs is the presence of a vortex rim mounted on the rear disc of the impeller. The geometric parameters of the rim greatly affect the characteristics of the stage, both when pumping a pure liquid and a gas-liquid mixture.

The article presents the main results of bench tests of mini-sections of electrically-driven vane pumps when pumping a gas-liquid mixture. The stages of the sections are centrifugal-vortex with different geometry of the vortex rim. The results of the tests carried out are the dependences of the pressure created by the mini-section of the EVP with different geometric parameters of the vortex rim when pumping a gas-liquid mixture, on different absolute pressure at the inlet. A conclusion is made about the different ability of centrifugal-vortex stages to pump a gas-liquid mixture at the same inlet pressures.

Hydrocarbon raw materials, the main representative of which is oil, is the most important object of the fuel and economic complex of any developed state. The necessity of development of the northern hard-to-reach deposits, the developed, but low-yield ones require special attention today. Low-yield wells need to maintain stable oil production rates based on the introduction of modern technologies and equipment for maintaining oil recovery. The article analyzes the possibility of operating a low-flow-rate well stock using an oil jet pump. Domestic and foreign analogues, regulatory and technical documentation are analyzed. This made it possible, after evaluating the design features, to determine the main qualitative characteristics of an oil jet pump (flow, pressure, power, efficiency) and to develop a methodology for testing them. A research bench complex of certification tests is presented and an algorithm for conducting them to confirm the quality of an oil jet pump is developed.

The article considers the main results of theoretical and full-scale experiment on static loading of a tubular plastic element by concentrated transversely applied forces. As a result of obtaining separate experimental data, a number of diagrams subject to testing of tubular elements with clearly marked so-called "double" yield points in the wP1 plane, and less expressed in the wP2 plane were revealed. The data obtained indicate significant discrepancies in the expected and obtained results of field experiments and can claim to identify a new physical phenomenon that is not considered in the course of the classical theory of elasticity and plasticity.

One of the trends of improving positive displacement motors (PDM), used for drilling oil and gas wells and increasing their operational showings is optimization of the geometric parameters of the cycloidal gearing of motors working parts. The article considers the influence of evolution of the cycloidal face profile on the geometric and kinematic parameters of the PDM and offers a generalized table of the effect of dimensionless coefficients on the cycloidal gearing characteristics, which allows optimization of the profile based on geometric and kinematic criteria generalized in the objective function. The analysis of the evolution of the cycloidal profile shape showed that, if it is necessary to modify the power section due to varying by the dimensionless geometric coefficients (while maintaining the smoothness of the contours), the useful area can be changed in a wide range, and the maximum value of the area refers to the cycloidal gearing with the minimum numerical values of the geometric coefficients. This allows a more reasonable approach to the cycloidal profile design and selection of its optimal parameters for various types of drill bits and diametrical dimensions of the motor. The proposed methodology can also be used when designing the end profile of gerotor hydraulic machines.

The results of pilot work on the pumping of Russian pseudo-plastic polymer system to increase oil production rates and reduce water-flooding in the Zhalgiztobe layered inhomogeneous oil field (Republic of Kazakhstan), the oil viscosity of which is 846 MPa and wells oil flow 1,3 t/day and high water flooding of 80...90 %, conducted in December 2019, are presented. To substantiate the technology, laboratory experiments were carried out, which allowed choosing the concentration and volumes of the reagent fractional slug 5,3 tons of the dry reagent was injected during the pilot operation. Efficiency evaluation by the method of displacement characteristics showed a technological effect for 21 months after the pilot operation in the amount of more than 2000 tons of additionally produced oil (increase in oil production rates made 45 %) with a decrease in water flooding by 2 %. The technological effect amounted to more than 400 tons of additionally produced oil per 1 ton of the injected dry reagent. In accordance with the mechanism of waterproofing polymer technologies, the total technological effect is expected to be even greater. Since more than 5 % of oil reserves in the Russian Federation belong to the category of high viscosity oils, the experience of using the Russian pseudo-plastic polymer system to increase oil production rates and reduce water flooding at such facilities is very important for the Russian Federation.

This paper describes the filtration process of a multicomponent multiphase fluid high-viscous oil with solid (in the extreme) inclusions, deposits of bitumen, paraffin or asphalt-resin-paraffin deposits in the reservoir. Under the influence of high-frequency electromagnetic radiation due to the field energy absorption, the formation and fluids are getting heated, resulting in the phase transition of solid inclusions into the liquid state. The impact of high-frequency electromagnetic heating is intensified by simultaneous injection of an agent miscible with formation fluid into the formation. The paper presents a model of miscible displacement of fluid by the agent, considering phase transitions under the influence of high-frequency electromagnetic fields. Special attention is paid to mathematical modeling of thermobaric conditions of non-isothermal process, i. e. PVT-properties of formation fluids. A new approach to building a unified non-isothermal PVT-model for numerical solution of the mathematical model of the process is presented.

When developing and operating gas and gas condensate fields as well as reserving natural gas in underground gas storage facilities, there often arise situations associated with gas abrasive and hydro-abrasive wear of field equipment, formation of clay-sand plugs in wellbores, partial or complete plugging of gas-gathering networks, etc. Similar situations occur when, together with the gas, formation sand (rock) and liquid are carried out and hydrate structures of various compositions are formed. The simultaneous presence of solid mechanical impurities and liquid in natural gas complicates the supply of hydrocarbon raw materials to the consumer, requires an increased load of cleaning systems and preparation of a conditioned product. The worst scenario with unacceptable levels of sand and liquid content in well production is the occurrence of emergency situations due to abrasive wear of pipelines and valves, which leads to their shutdown and subsequent expensive repairs. On the other hand, serious risks are caused by the formation of complexly composed hydrate structures, which also leads to increased consumption of the inhibitor, partial or complete interruption of natural gas supply to the consumer, increased wear of field equipment, loss of produced products, environmental pollution and significant costs for repair and recovery activity.

The paper considers the problems of pipelines testing. In particular, the experience of conducting hydraulic testing is analyzed and the characteristic features and advantages of hydraulic shock testing are presented.

It is shown that the conditions of a pipeline section impact testing are limited mainly by the mechanical properties of the pipe metal, the error of the testing method and the properties of the measuring instruments. The parameters of hydraulic testing the value of the pipelines testing load, the permissible range of pressure increase rate are substantiated on a specific example.

The aftereffects of loads impact on the pipeline, which are controlled hydraulic shocks, are analyzed. Application of the acoustic-emission method of non-destructive testing allowed getting the characteristics of the shock wave, when it passed along the section of the pipeline. The maximum energy jump in the pipe and the wave propagation rate are revealed.

The authors of the paper also draw attention to the necessity of additional research and the development of a methodology for conducting impact tests during the overhaul of pipelines, which, unlike new ones, are characterized by different deformation properties and the level of residual stresses.

The loss of petroleum products due to evaporation remains one of the strategically important problems in the field of raw materials transportation and storage. Despite numerous studies on the issue of recovery, there are various obstacles that do not allow completely minimization of light hydrocarbons loss followed by their return to the production process. Also, it should be noted that the process of vapor return is complex and includes several stages: cooling or sorption with solid absorbers, followed by the oncoming flow condensation of a homogeneous liquid. It is required for solving the set task as well as "ensuring the reduction of the negative impact of economic and other activities on the environment in accordance with the environmental standards, which can be achieved through the use of the best available technologies, taking into account economic and social factors" [1].

The utility model proposed by the authors of the article refers to the oil and chemical industry, namely, to the devices used for top loading of light and dark petroleum products into tank cars and tank trucks on railway loading platforms, as well as auto-filling points of oil depots, oil refineries and end points of main oil pipelines.

The purpose of the study is to identify the possibilities of alternative methods for reducing the loss of petroleum products from evaporation during filling operations directly on the loading racks.

The scientific novelty and practical significance of the work presented by the authors consists of a utility model development that allows significant reduction of light oil products loss, as well as to minimization of the negative impact of the released vapors on the environment and personnel serving the overpasses.

The main advantages of this development are versatility, ease of installation and ensuring sealing at the joints of the filling device with the neck of the tank car. Therefore, the implementation and use of the developed technological solution will significantly reduce the loss of petroleum products from evaporation during filling operations, which will significantly decrease commercial losses.
