Device for controlling oil-water interface of split equipment

Abstract

The invention provides a device for controlling an oil-water interface of split equipment, and relates to the technical field of crude oil treatment. The device comprises an oil-gas-water separator and a settling water purification tank, the oil-gas-water separator is communicated with the settling water purification tank, and a floater connecting rod mechanism is arranged at the upper end of the settling water purification tank and comprises a floating ball, a connecting rod and a control valve. The floating ball is arranged in the settling water purification tank, the connecting rod penetrates through the outer wall of the settling water purification tank and is fixedly connected with the floating ball, and the end, away from the floating ball, of the connecting rod is fixedly connected with a control valve. By arranging the floater connecting rod mechanism, the liquid level of the oil-gas-water separator can be controlled, the liquid level of the settling water purifying tank can be controlled, and the technical problems that an oil-water interface can be adjusted only after production stopping and tank cleaning, the process is complex, consumption is large, and the period is long can be solved.

Description

technical field [0001] The invention relates to the technical field of crude oil treatment, in particular to a device for controlling the oil-water interface of split equipment. Background technique [0002] The oil-gas-water three-phase separator is one of the most commonly used equipment in the oilfield development and production process. It is a "solid, liquid and gas" three-phase separation device installed under the pump in the oil-water well of the oilfield. The oil-gas-water mixture enters the pre-degassing chamber at high speed, and a large amount of crude oil associated gas is released by cyclone separation and gravity. Washing and demulsification in the layer, stabilize the flow, reduce the Reynolds coefficient of the incoming liquid, and then flow into the sedimentation and separation chamber after coalescence and rectification for further sedimentation and separation. Then it flows out of the separator, and the water phase enters the water chamber through the co...

Problems solved by technology

[0004] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a device for controlling the oil-water interface of split equipment, which can solve the problem that the oil-water interface needs to be shut down and adjusted after the tank is cleaned. The process is relatively complicated and the cost is relatively large. Technical problems with a relatively long cycle
