Purpose: of this paper is to analyze the possibility of increasing the efficiency of wellbore jet pumps by twisting the injected flow. The absence of moving parts, easy transfer of energy, the ability to operate a wide range of performance and low cost have resulted in the use of ejection systems in many oil and gas deposits. The main disadvantage of borehole ejection systems is the insufficient value...
The article is devoted to the theoretical study of the operation process of the borehole ejection system as part of the tubing string, jet pump and packer installed below; the system implements the hydrojet method of oil well operation. The improved design of the jet pump contains inclined guiding elements placed in its receiving chamber for swirling the injected flow, which results in an increase...
