Gas-liquid separation device and method, crude oil extraction system and crude oil detection system

Abstract

The invention belongs to the technical field of petrochemical equipment, and relates to a gas-liquid separation device for fluid obtained by extracting crude oil light dydrocarbon through high-pressure gas, which comprises a shell, at least two fluid introduction pipelines, a liquid drainage pipeline and a liquid collector. The shell is provided with a fluid inlet, a gas outlet, a liquid outlet, acondensing medium inlet and a condensing medium outlet. The at least two fluid introduction pipelines and the liquid drainage pipeline are positioned in the shell. All the fluid introduction pipelines are communicated in sequence, the included angle between each fluid introduction pipeline and the horizontal plane is greater than 0 degree and less than or equal to 90 degrees, the lower end of each fluid introduction pipeline is communicated with the upper end of the liquid drainage pipeline, the upper end of a first fluid introduction pipeline in the at least two fluid introduction pipelinesis communicated with the fluid inlet, and the upper end of a last fluid introduction pipeline is communicated with the gas outlet. The lower end of the liquid drainage pipeline, the liquid outlet andthe liquid collector are sequentially communicated. The gas-liquid separation device can quickly realize gas-liquid separation under the condition of high pressure.

Description

technical field [0001] The invention belongs to the technical field of petrochemical equipment, and more specifically relates to a gas-liquid separation device, a gas-liquid separation method, a crude oil extraction system, and a crude oil detection system for fluid obtained by extracting light hydrocarbons from crude oil with high-pressure gas. Background technique [0002] The high-temperature and high-pressure physical properties (PVT) parameters of crude oil are widely used. They are indispensable data for reservoir simulation and reservoir engineering calculations, and are the basis for studying reservoir driving types, calculating reservoir reserves, and determining oilfield development methods. [0003] The practice of oil and gas field development and production shows that, in addition to pure gas reservoirs, the development, production and surface technology of condensate gas reservoirs and oil reservoirs will experience fluid phase states such as mutual dissolution ...

AI Technical Summary

Problems solved by technology

Due to the narrow space of the Erlenmeyer flask and the condition of normal pressure, the separation effect is poor, and a large amount of liquid light hydrocarbons are retained after the fluid cools down, resulting in large errors in the measurement of the gas-oil ratio of the fluid and some related physical parameters.
