GAS SEPARATOR OF INSERT OIL-WELL PUMP

摘要

FIELD: oil industry, particularly to operate oil wells with high gas factor and with the use of inserted tubing pumps. ^ SUBSTANCE: body with conical seat is connected to flow string. Liner provided with suction valve in lower part thereof is joined to the body. Deep-well sucker-rod pump is installed in conical seat provided with seals. Arranged in receiving chamber of the sucker-rod pump is sliding piston with injection valve. Receiving chamber has suction valve. Cavities separated from hole clearance with membranes are arranged in the body. The membranes may sustain extreme pressure. Cavity is hydraulically communicated with liner interior through channel. Fishing chamber is arranged in the body. ^ EFFECT: possibility of emulsified oil and gas mixtures having increased gas factor production with the use of inert oil-well pumps provided with liners. ^ 2 cl, 2 dwg
