Abstract

A borehole ejector relates to devices for oil extraction from wells operated with rod well pumps. The ejector has working nozzle, receiving chamber, mixing chamber, diffuser, check valve and body. The check valve connects the annular space with the suction cavity of the ejector. The body is connected to the pump-compressor tubes. In the central opening of the body there is media separator. It comprises two semi-cylindrical bodies connected to each other with threaded joint, and has central long opening for passage of the rod of the pump unit. At beneath the separator rests on the spring ring with sealing gasket, and at above it is stopped with a holder. The ejector is installed above the dynamical level of the well. At passage of oil through the ejector gas from annular space is sucked and mixed to it. Due to decrease of density of gas-liquid mix and effect of gaslift its lift to the surface and support of dynamical level of the well are facilitated.
