DEVICE FOR PUMPING GAS FROM ANNNULAR SPACE Russian patent published in 2023 - IPC F04B35/01 E21B43/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the field of oil and gas industry and is intended for pumping gas from the annulus of wells equipped with downhole rod pumps. In a device for pumping gas from the annulus of wells equipped with pumping units, including a compressor cylinder, a piston, working chambers formed by a piston and a compressor cylinder, a suction line with a valve connecting the compressor cylinder to the well annulus and a discharge line with a valve connecting the cylinder compressor with a flow line of the well, the compressor consists of two identical cylinders placed vertically symmetrically with respect to the polished rod and perpendicular to the plane of the major axis of the pumping unit, the pistons of the cylinders are connected by rods through a rocker arm fixedly fixed on the polished rod, and the lower ends of the two cylinders are placed as close as possible to surface of the well pad and fixed by the frame to each other.

EFFECT: increasing the reliability of the device for pumping gas from the annulus of wells and increasing the productivity of its work.
