Gas Lift

A method of artificial lift used in oil wells to increase the flow of hydrocarbons from a reservoir. It involves injecting gas (such as natural gas or CO2) into the wellbore to reduce the density of the fluid column, thereby increasing the pressure differential and lifting the fluid to the surface. / 一种用于油井的人工举升方法，通过向井筒注入气体（如天然气或CO2）降低流体柱密度，从而增加压差并将流体举升至地面。
