Abstract

The invention provides a two-stage tubular gas-liquid separator suitable for wide-range change of inlet gas content, relates to the technical field of oil and gas gathering and transportation treatment processes and equipment of oil and gas fields, and provides a two-stage tubular gas-liquid separator which is suitable for wide-range change of inlet gas content, high in separation efficiency and compact in structure. By combining the first-stage horizontal separation section which depends on centrifugal force for separation and the second-stage vertical separation section which depends on'gravity and centrifugal force 'for separation, the high adaptability to large-range change of the gas content of an inlet is realized. A gas phase outlet pipe in the first-stage horizontal separation section adopts a conical multilayer annular special design, so that the influence of working condition fluctuation on the separation process in the separation process can be effectively reduced; and an inner cylinder is designed and mounted in the second-stage vertical separation section, so that adverse effects caused by fluctuation of gas-liquid working conditions can be reduced.

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 oil and gas reservoirs, the life of oil wells and the changes in 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 separation. Ther...
