Symmetrical gas-liquid separator

Abstract

The invention discloses a symmetric gas-liquid separator; the symmetric gas-liquid separator comprises a main body pipeline and a plurality of acceleration rotation assemblies, and each acceleration rotation assembly comprises at least one acceleration rotation device; a cavity is formed in the main body pipeline, the plurality of acceleration rotation assemblies are arranged in the cavity, and each acceleration rotation assembly is arranged in the radial direction of the main body pipeline; on the axial projection surface of the main body pipeline, the plurality of acceleration rotation assemblies are distributed in a staggered manner; the transverse section, in the axial direction of the main body pipeline, of the acceleration spiral flow generator is of a symmetrical structure relative to the radial direction of the main body pipeline; and the acceleration spiral flow generator comprises a plurality of acceleration spiral flow generator sets, and the two acceleration spiral flow generators in each acceleration spiral flow generator set are symmetrical about the axial direction of the main body pipeline. The symmetric gas-liquid separator solves the problem that in the prior art, gas-liquid separation is not ideal when gas content is high or gas treatment capacity is high.

Description

technical field [0001] The invention relates to the field of gas-liquid separation, in particular to a symmetrical gas-liquid separator. Background technique [0002] In the oil extraction industry, some oilfield blocks will encounter high gas content production fluid or a large amount of gas treatment. The production fluid contains oil, gas, water and sand, and the gas in it can be divided into dissolved gas and free gas. Gas itself exists in the form of gas and is easy to separate, while dissolved gas is the part of gas dissolved in oil or water under certain conditions and is not easy to separate. [0003] In the produced fluid with high dissolved gas content, not only the crude oil contains high dissolved gas, but also the produced water also contains a large amount of dissolved gas, which exists in the liquid in the form of small bubbles. The method of separating dissolved gas in existing equipment is to put the produced liquid in a state of normal pressure and degas i...
