Description

Technical Field

[0001] This utility model belongs to the technical field of liquid discharge separation devices, specifically an automatic liquid discharge separation device for gas-liquid two-phase flow gathering and transportation pipelines. Background Technology

[0002] In the field of oil and gas extraction, the gathering and transportation system is a crucial link in transporting the mixed fluid produced at the wellhead (typically containing crude oil, natural gas, formation water, and a small amount of solid impurities) from the well site to the processing station or terminal. For scenarios such as low-pressure, low-production wells, remote wells, or offshore platforms, due to limitations in economics, geographical conditions, or process requirements, gas-liquid two-phase mixed transportation technology is often adopted. This involves directly transporting unseparated gas and liquid through the same pipeline, and then separating them through a liquid separation device.

[0003] Existing liquid separation devices have relatively complete structures and functions, and can meet basic usage requirements, but they still have the following problems:

[0004] In actual use, after the liquid and gas are separated, the gas will be discharged from the top of the separator, while the liquid will be discharged from the bottom outlet pipe. During the gas discharge process, fixed particles or liquid will be discharged, which will affect the purity and quality of the gas, which is very inconvenient. Utility Model Content
