Petroleum purification elevation angle type three-phase separator and petroleum comprehensive treatment system

Abstract

The invention relates to the field of petroleum drilling and production, and discloses a petroleum purification elevation angle type three-phase separator and a petroleum comprehensive treatment system, one end of a steel tank body is indirectly controlled to ascend and descend through a hydraulic cylinder, so that a corresponding tank body elevation angle is determined, and the smaller the tank body elevation angle is, the smaller the tank body elevation angle is. By arranging the oil-water separation coalescer, the separation proportion area of a gas-liquid mixture on the oil-water separation coalescer after the gas-liquid mixture enters the steel tank body is smaller, so that the separation rate is smaller, the separation rate is controllable, and by arranging the impurity removal pipe, the gas-liquid mixture can be filtered and purified by the filter before entering the gas-liquid inlet, so that larger solid impurities are prevented from entering the steel tank body, and the separation efficiency is improved. The advantages of the vertical separator are embodied, the pressure intensity in the steel tank body is detected in real time through the pressure intensity detector, if the internal pressure is too large, the controller controls the first electromagnetic valve to be closed and the second electromagnetic valve to be opened, a gas-liquid mixture is discharged into the pressure relief tank, and continuous pressurization, damage to internal elements of the steel tank body and the overflow phenomenon are avoided.

Description

technical field [0001] The invention relates to the field of oil drilling and production, in particular to an elevation angle three-phase separator for oil purification and a comprehensive oil treatment system. Background technique [0002] At present, oilfields at home and abroad usually adopt the method of gravity sedimentation for three-phase separation of oil, gas and water. In the process of oilfield production, [0003] In practical applications in oil fields, the gas-liquid separation interface in the vertical separator is small, and the gas-liquid separation effect is relatively poor; the gas-liquid separation interface in the horizontal separator is large, and the gas-liquid separation effect is good, but the liquid level is small, and the drainage The distance between the port and the oil-water interface is short, the oil-water separation effect is poor, and the tank bottom area is large and covers a large area. reduce. [0004] In view of the limitations of hori...
