Deterioration of the qualitative and quantitative characteristics of the hydrocarbon resource base leads to an increase in the share of hard-to-recover reserves. In an environment where the share of hard-to-recover oil reserves in the oil industry is steadily increasing, the need to create effective methods to increase oil recovery is acute. The method of flooding at the present stage of the development of the oil industry is considered the most progressive, meeting the basic principles of oil field development. However, during flooding, a large proportion of oil reserves remains in the reservoir, and therefore, technologies are currently being sought and developed in all major oil companies that will increase the oil recovery coefficient. Currently, there is a growing interest in the application of the technology of water-gas exposure to oil formations to increase oil production. This is due to the fact that the water-gas effects combine the positive aspects of well-known oil production technologies, such as flooding and the method of pumping hydrocarbon gas into the reservoir. Experimental and theoretical studies have established that one of the most effective methods of oil recovery can be methods based on injection of hydrocarbon gases and water-gas mixtures into the reservoir. Experiments were conducted to study the mechanism of displacement and determine the coefficient of displacement of oil by gases and water in various combinations in relation to some fields. The experiments were carried out under conditions as close as possible to reservoir conditions: recombined or reservoir oil samples, core from productive deposits were used. The pressure and temperatures corresponded to their reservoir values. As the results of experiments, the increase in the oil displacement coefficient depends on the type of gas injected (hydrocarbon equilibrium and nonequilibrium with reservoir oil, acidic, inert, etc.) and modification of the injection technology of agents (sequential, alternate, joint). To study the expected results of testing the technology of water-gas exposure at the Kalamkas field, the experience of using this method at other fields is considered. The paper presents an analysis of the experience of implementing the technology of water-gas exposure at various locations. A review analysis of the results of the technology implementation was carried out to determine the advantages and possibilities of using the technology of watergas exposure in the conditions of the Mangystau field.

“…Concerning the features of the design of modern ejection systems that are operated under aggressive conditions, some authors suggest the use metallic ceramics or ceramic coatings to provide the required operational life of the nozzle [60][61][62]. Recommendations have been made on the technology of forming, optimal design and calculation of the operational properties of single layer [63,64], flexible [65,66] or multilayer ceramic coatings [67][68][69]. Thermoplastic composite materials are also widely used [70][71][72][73].…”

During oil fields operation, gas is extracted along with oil. In this article it is suggested to use jet pumps for utilization of the associated oil gas, burning of which causes environmental degradation and poses a potential threat to the human body. In order to determine the possibility of simultaneous application of a sucker-rod pump, which is driven by a rocking machine, and a jet pump (ejector) in the oil well, it is necessary to estimate the distribution of pressure along the borehole from the bottomhole to the mouth for two cases: when the well is operated only be the sucker-rod pump and while additional installation of the oil-gas jet pump above its dynamic level. For this purpose, commonly known methods of Poettman-Carpenter and Baksendel were used. In addition, the equations of high-pressure and low-pressure oil-gas jet pumps were obtained for the case, when the working stream of the jet pump is a gas-oil production mixture and the injected stream is a gas from the annulus of the well. The values which are included in the resulting equations are interrelated and can only be found in a certain sequence. Therefore, a special methodology has been developed for the practical usage of these equations in order to calculate the working parameters of a jet pump based on the given independent working parameters of the oil well. Using this methodology, which was implemented in computer programs, many operating parameters were calculated both for the well and for the jet pump itself (pressures, densities of working, injected and mixed flows, flow velocities and other parameters in control sections). According to the results of calculations, graphs were built that indicate a number of regularities during the oil well operation with such a jet pump. The main result of the performed research is a recommendation list on the choice of the oil-gas jet pump location inside the selected oil well and generalization of the principles for choosing the perfect location of such ejectors for other wells. The novelty of the proposed study lays in a systematic approach to rod pump and our patented ejector pump operation in the oil and chrome plating of pump parts. The result of scientific research is a sound method of determining the rational location of the ejector in the oil well and the calculation of its geometry, which will provide a complete selection of petroleum gas released into the annulus of the oil well. To ensure reliable operation of jet and plunger pumps in oil wells, it is proposed to use reinforcement of parts (bushings, plungers, rods, etc.) by electrochemical chromium plating in a flowing electrolyte. This has significantly increased the wear resistance and corrosion resistance of the operational surfaces of these parts and, accordingly, the service life of the pumps. Such measures will contribute to oil production intensification from wells and improve the environmental condition of oil fields.
