Abstract:

The scope of downhole ejection systems is limited by the low value of the efficiency of the jet pump, the value of which usually does not exceed 35 %. Significant energy losses when mixing flows are the reason for the low efficiency of the jet pump. The energy performance of the downhole ejection system can be increased by creating swirling vortex circulating currents in the flow part of the jet pump. This optimizes the nature of the flow mixing and increases the energy performance of the jet pump. In the process of studying the structures, features of the working process and usage experience

Abstract:

Insufficient energy performance of ejection equipment and a high probability of non-operating modes of its operation reduce the efficiency of downhole jet pumps. The method of determining the design and operating parameters of the well ejection system, which provide the maximum efficiency of the jet pump, is presented. The proposed algorithm for determining the optimal values of the geometric dimensions of the flowing part of the jet pump involves the construction of a series of pressure characteristics for different values of its geometric parameter, the calculation of the efficiency and the

Abstract:

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 an

Abstract:

The development trends of hydraulic jet pumps used for the oil-fields exploitation are analyzed. The ambitionto optimize the process of mixing flows has led to the emergence of numerous designs of jet pumps, in which swirling flows are used instead of direct flows. The creation of circulation flows in the pump wet end promotes alignment of coaxial flows velocities, intensifies the process of energies exchange in the liquid, and increases the efficiency of the mixing process. The combination of direct and circulation flows gives a possibility to improve the technical characteristics of jet pump

Abstract:

The Hutton zone of the Tintaburra oilfield has an active bottom water drive which necessitates high gross fluid production rates to enable reserves to be produced within a reasonable period of time. A high volume artificial lift system capable of producing 8 000 to 10 000 barrels of fluid per day (BFPD) from 6 producing wells formed the basic design criteria, and hydraulic jet pumping was chosen as the means of artificial lift. The hydraulic jet pumping installation at Tintaburra was the first of its kind in Australia.The basic principle of operation of a jet pump is the transfer of momentum f

Abstract:

The purpose of the study is to develop a supra bit jet pump taking into account the unsteadiness of low-speed drilling for crushing the cuttings injected from the annular space under productive formation opening. The article proposes a device for drill string bottom assembly intended for the initial opening of the productive formation. The device includes a supra bit jet pump and a colmatator. The jet pump creates an additional circulation loop of the drilling fluid above the well bottom, crushes the cuttings injected from the annular space in the mixing chamber and delivers it to the colmatat

The hydraulic model of low-pressure jet pump working process for conditions of its asymmetric rotation is proposed on the basis of law of conservation of liquid momentum of parallel mixed potential flows with linear distribution of tangential velocities and radial displacement relative to borehole axis. In the process of derivation of the equation of pressure characteristic of low pressure jet pump at its asymmetrical rotation in a borehole the law of conservation of flow energy in the form of Bernoulli's equation and the law of continuity conservation of mixed currents have been used.

Abstract:

Abstract The article proposes a jet pump for the bottom hole assembly. The developed supra-bit jet pump provides an additional circulation loop of the drilling fluid above the bottom of the well, which creates a local depression of the formation. In addition, the jet pump grinds the sludge injected from the annular space in the mixing chamber and feeds it to the bridging machine, which is included in the assembly, for temporary isolation of the productive formation. Isolation of the productive formation is necessary to prevent the flow of formation fluids into the wellbore when underbalanced.

Abstract:

In order to test the operational efficiency of jet pumps which are installed at different depths in artificial lift-ed oil wells, it is necessary to establish the relation between their geometry and the maximum achievable operat-ing parameters. For this purpose, a series of experimental laboratory studies is conducted. Their main task is to identify the optimal parameters of a jet pump that works with gas-liquid flows. In the experimental setup, the fluid is supplied by an electric centrifugal pump and the air is injected by a compressor. The setup provides the possibility to regulate the flui
