Background
A plunger gas lift water drainage and gas recovery process is a water drainage and gas recovery method which accumulates reservoir energy by means of intermittent well opening and closing and further discharges accumulated liquid in a shaft by pushing a plunger in an oil pipe to reciprocate up and down to develop natural gas. The process principle is as follows: when the pneumatic valve is closed, the plunger automatically falls to a clamping device arranged at the bottom of the production string under the influence of the gravity of the plunger, and the liquid level in the oil pipe continuously rises and exceeds the height of the plunger. When the pneumatic valve is opened, the gas quickly enters the oil pipe, and pushes the plunger and the liquid on the plunger to rise to the well mouth together with the gas flowing into the well bottom from the stratum until the liquid on the upper part of the plunger is lifted to the ground, so that the liquid is discharged out of the well shaft, and the natural gas is produced. And when the formation pressure needs to be recovered after the gas well is produced for a certain time, the pneumatic valve is automatically closed, the plunger falls down, and the next working cycle is started. Because the plunger piston and the oil pipe are in interference fit in the process, the resistance of the interference fit and the lifting force of fluid in the well are overcome when the plunger piston descends, so that the plunger piston descends slowly, and the production efficiency of the gas well is influenced.
