FIELD: oil industry.
SUBSTANCE: invention relates to the oil industry and can be used to bleed associated gas into the tubing line of a production well operated by a mechanized method. The installation for extracting gas from the annulus of an oil well includes a working container with a float configured to interact with maximum and minimum level sensors, an inlet gas line connected to the annulus of the well, and an outlet gas line connected to the flow header of the well. The installation additionally comprises suction and discharge valves installed respectively on the inlet and outlet gas lines, a device for pumping the working fluid, a fluid inlet line that is connected to the pressure side, a fluid outlet line connected to the feed tank through a fluid flow switch functionally connected to the unit control receiving signals from liquid level sensors. At the same time, the annulus of the well is used as a nutrient reservoir communicated with the liquid outlet line. The liquid outlet line is equipped with an adjustable drain valve control unit. The suction and discharge valves are made by adjustable control unit to open the suction valve and drain valve and close the discharge valve and flow switch when the liquid is drained and the working tank is filled, as well as the suction valve and drain valve are closed and the discharge valve and flow switch are opened when the working tank is filled with liquid and squeezing gas out of it through the outlet gas line into the discharge manifold. At the same time, a bypass line was used as the liquid inlet line, connected to the discharge manifold by a flow regulator to select part of the pumped liquid into the working tank through the bypass line and the flow switch. As a device for pumping the working fluid, a submersible pump is used, which pumps out the reservoir fluid from the well and communicates with the discharge manifold.
EFFECT: improving the efficiency of the downhole pump, reducing emergency situations.
