Example Embodiment

[0022]The following is a detailed description of the description of the present invention in conjunction with the drawings, which is apparent from the examples, and is merely the embodiments of the present invention, not all of the embodiments.

[0023]Such asfigure 1As shown, a means for controlling the oil-water interface of the split apparatus, comprising an oil-air water separator 1 and a settling cleaning tank 2 having a hollow structure having a cavity, the oil and gas water separator. 1 It can be separated from the oil and gas water, the top of the oil and gas water separator 1, which is connected to the settling cleaning tank 2 at the top of the oil and gas water separator 1. A first valve 7 is provided on the first conduit 6, separating the oil, gas, water mixture contained in the crude oil by the oil and gas water separator 1, and the gas is discharged through the first exhaust port, and the separated oil is collected. In the tank, the sewage is stored in the settling cleanin...

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...
