The utility model discloses a using and installing method of an automatic drainage system for an oil and gas field with multiple dry pumping prevention protection, which comprises the following steps:

(1) fixedly mounting a controller at a laying cable source end (a dry place); the pump pry is vertically placed at a position needing water drainage, and the pump pry refers to a device whole consisting of a frame, a water drainage pump, a floating ball liquid level meter, a junction box and the like. The pump pry is kept horizontally arranged to ensure that the floating ball works normally. If the pump skid tilts during installation, it can result in: firstly, the liquid level controller can not operate when the water level reaches the pump starting condition. Secondly, when the water level reaches the pump stopping condition, the pump control cannot be stopped normally.

(2) And adjusting the drainage pump and the floating ball liquid level meter to proper positions and rightly and firmly fixing the drainage pump and the floating ball liquid level meter.

It is desirable to place the drain pump in a flat position where the drainage is low in topography to ensure that the drain is able to drain as much water as possible. When the drain is required to maintain the maximum dryness therein, the installation position of the drain pump of the device should be preset in the drain to ensure that the suction port of the drain pump can absorb as much water as possible in the drain.

When the drainage pump is adjusted to the lowest position, the water suction pipe of the pump can exceed the bottom surface of the frame, and the installation mode is suitable for the condition that a water accumulation gathering pit foundation is preset at the drainage position.

And a low-level water suction port is adopted, so that smooth water inlet is ensured, and little or no accumulated water in the tank after water drainage is ensured as much as possible. In addition, the stressed supporting piece needs to be unfolded, the stability of the prying body is improved, and the prying body is prevented from sliding into a accumulated water gathering pit to cause the inclination of the prying body.

The drainage system of the utility model adopts the low-level water suction port, simultaneously ensures smooth water inlet, ensures little and no accumulated water in the pool after drainage as far as possible, the weight is born by the prying body after installation, and the pump is lifted by the prying body, thereby preventing the ground from being damaged after long-time operation. The position of the draining pump can be adjusted up and down, and a prying body can be normally installed at a place without a preset accumulated water collecting pit. However, when the collecting pit is not available, the accumulated water with the thickness of about 20mm can be left and cannot be drained. When a preset pit is arranged, the pump opening can be adjusted to be below the ground level, and the drying degree of the position needing to be drained is ensured as far as possible.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
