Abstract

The invention provides a double-stage tubular gas-liquid separator adapting to the wide variation of inlet gas content, and relates to the technical field of oil and gas gathering and transportation processing technology and equipment in oil and gas fields. , Two-stage tubular gas-liquid separator with high separation efficiency and compact structure. The present invention realizes the high adaptability to the large-scale variation of the inlet gas content by combining the first-level horizontal separation section separated by centrifugal force and the second-level vertical separation section separated by "gravity + centrifugal force". The gas phase outlet pipe in the first-level horizontal separation section adopts the special design of conical multi-layer ring, which can effectively reduce the influence of working condition fluctuations on the separation process during the separation process; the inner cylinder is designed and installed in the second-level vertical separation section, which can reduce the The adverse effects of small gas-liquid fluctuations.

Description

technical field [0001] The invention relates to the technical field of oil and gas gathering, transportation and processing technology and equipment in oil and gas fields, in particular to a double-stage tubular gas-liquid separator that adapts to the wide variation of inlet gas content. Background technique [0002] In the upstream field of the petroleum industry, the output of oil wells inevitably contains a certain amount of associated gas, and its content often changes with the geological conditions of the oil and gas reservoir, the life of the oil well and the changes in the production pressure. It will vary from 10% to 90%. The important task of oil and gas gathering, transportation and processing is to effectively implement gas-liquid separation, oil-water separation and other processes to obtain natural gas, crude oil and oilfield produced water that meet the corresponding requirements. The gas-liquid separation process is usually carried out before oil-water separat...
