成果简介	NOVELTY - Invention relates to oil and gas industry and can be used for gas extraction from annular space of a production well equipped with a borehole pump. Claimed plant for extraction of gas from annular space of production well, including control unit, sensor of the maximum and minimum measured value for switching the operating modes of the installation using the control unit, a supply gas line connected to the annular space of the well, a discharge gas line with an injection valve, which is connected to a discharge manifold of the well, and a pump with an electric motor, which is lowered into the well. Pump is fixed outside one of the process pipes of the production tubing, which is interconnected with the discharge header of the submersible production pump above the level of the well fluid and is connected to the control unit by a supply cable. Sensor of the maximum for switching on the pump and the minimum for switching off the pump of the measured value is made in the form of a wellhead pressure sensor functionally connected to the control unit. Inlet gas line is made in the form of a mesh or slotted filter at the pump inlet, and the outlet one is in the form of a side hole of the process pipe connected through a pressure valve to the pump outlet. USE - Oil and gas industry. ADVANTAGE - Simplification of design for gas extraction from annular space of production well and increase of its reliability due to arrangement of pump above level of well fluid, its periodic operation and exclusion of controlled valves. 4 cl, 1 dwg
