How does Gas Lift Valve work?

The working principle of gas lift valve is very simple, which is the inlet and outlet switch of gas lift! Take the casing pressure operation valve (the most commonly used) as an example, when the casing pressure acts on the envelope surface and the pressure in the oil pipe acts on the ball valve, when these two forces are greater than the pressure in the envelope, compress the envelope (NND, which is the gas chamber, where the injection is usually nitrogen, and figure it out by yourself), lift the ball valve, and the gas lift begins to enter the oil pipe. When the gas enters the tubing at high speed, it will mix with the fluid in the tubing, so that the density of the mixture will be reduced, and then the pressure gradient will be reduced, so that the oil and water can rise at high speed.
