“…After this technology showed its effectiveness, such oil-gas jet pumps were proposed to be used together with sucker-rod pumps [27] or individually in complicated production conditions [28,29]. It should be noted here that a sucker rod string could be subjected to abnormal static and dynamic loads [30][31][32] especially for complex profile wells. Some authors [33][34][35] consider vibration reduction of oil equipment as a guarantee of dynamic stability of pump rod strings and ensuring the stability of submersible pumps.…”

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.

The article is devoted to the study of theoretical and methodological aspects of public-private partnership in the field of capital construction. In the context of globalization and the development of European integration processes, the need to improve the quality of life of the population and the introduction of European and world standards of life support makes the actual problem of improving the efficiency of housing and communal services and capital construction. The article defines that public-private partnership in today's conditions is one of the most progressive mechanisms of effective cooperation between the state (territorial community) and private business, which is carried out in order to increase the effectiveness of their functions by state and municipal authorities. Thus, based on the analysis of domestic practice of public-private partnership, the promising experience in implementing partnership projects of local governments and the private sector on the example of Ivano-Frankivsk is separated. In particular, the main aspects of cooperation between the local authorities of Ivano-Frankivsk and NEFCO in the implementation of energy saving programs are presented. It is noted that the basis of public-private partnership, as a rule, is the financial relationship between public authorities and representatives of private business. That is, it is about investing private capital in the development of state and communal property, necessarily on mutually beneficial terms. It is obvious that in the current conditions the implementation of projects in the field of capital construction by local authorities is practically impossible without the involvement of private partners in this process. At the same time, there are a number of factors and obstacles that in practice significantly complicate the process of establishing effective cooperation between the state and business. It is substantiated that public-private partnership is a kind of mechanism that provides certain benefits simultaneously for all its participants: the state, private business and the community. However, it has been proven that, as in any other economic relationship, there are some risks in a public-private partnership that are likely to create a threat to each party to the partnership.
