Abstract

The invention discloses a gas-oil-water separation system, comprising a swirl-type gas-oil-water separator (A), a swirl-type gas-oil separator (B) and a mist catcher (C); wherein, the swirl-type gas-oil-water separator (A) includes a first cylindrical barrel (1), which is provided with a first air outlet pipe (12), a first oil outlet pipe (13), a first input pipe (11), an outlet The water pipe (14), the cyclone type gas-oil separator (B) includes a second cylindrical shell (5), and the first air outlet pipe (12) is connected with the second input pipe (3) of the second cylindrical shell (5) The first oil outlet pipe (13) is in communication with the oil phase input pipe (51) on the second cylindrical barrel (5); the mist catcher (C) includes a tank body (6) and a droplet accumulation layer (7 ), the second air outlet pipe (52) of the second columnar body (5) communicates with the third inlet pipe (62) of the tank body (6). The present invention is not only applicable to the multiphase separation of oil wells and wet gas wells with different gas-oil ratios, but also adapts to the change of water content ratio from 0% to 100%. Check for accuracy.

Description

technical field [0001] The invention belongs to the technical field of fluid separation, and in particular refers to a gas-oil-water separation system that can finally realize the three-phase separation of gas, oil and water. The multi-phase separation of oil wells and wet gas wells with oil ratio can also be used to check the accuracy of current multi-phase flowmeters or gas-oil-water separation equipment. Background technique [0002] At present, in the oil field surface gathering and transportation system, various three-phase separators are mainly used to separate the natural gas, oil and water in the gas-oil-water mixture produced by the oil well, and then realize liquid metering or production metering. Traditional three-phase separators only rely on gravity to naturally separate gas, oil, and water. The oil content in the final output water is still high, and the separation effect is not ideal, and it is not suitable for use with different gas, oil, and water content ra...
