Automatic drainage device for accumulated water in square well of fixed oil-gas well

Abstract

The utility model discloses a fixed type oil-gas well square well accumulated water automatic discharging device which comprises an anti-explosion self-sucking pump, a water storage tank and at least one liquid level switch, an anti-explosion safety distance is arranged between the anti-explosion self-sucking pump and an oil-gas well square well, and the anti-explosion self-sucking pump is used for sucking accumulated water in a water pumping pit arranged at the bottom of the oil-gas well square well; a water outlet of the anti-explosion self-priming pump is positioned in the water storage tank; the liquid level switch is used for being installed in a water pumping pit. The liquid level switch and the anti-explosion self-priming pump are both electrically connected with the control end. The anti-explosion self-priming pump has the advantages that when the liquid level of accumulated water in the water pumping pit is at or higher than the liquid level switch, a high-level signal is sent out, the anti-explosion self-priming pump starts to drain water, when the liquid level in the water pumping pit is lower than the liquid level switch, a low-level signal is sent out, and the anti-explosion self-priming pump stops draining water. Operating parts such as valves are prevented from being located in accumulated water for a long time, normal operation of facilities is ensured, and equipment corrosion and instrument damage are prevented.
