Rationale for choosing the geometric dimensions of well hydraulic jet pump

Abstract

Barlow’s equation written for a thick-walled cylindrical shell a relationship was found between the stress that occurs in the material of the above-bit unit body and the flow of flush fluid for different designs of the borehole pump-circulation system and the jet pump flowing section. The study made it possible to determine the minimum allowable wall thickness for the above-bit ejection system, which facilitates its fault-free operation.
