A SYSTEM OF AUTOMATIC CONTROL PLUNGER LIFT IN GAS WELL

This paper introduced the principle and composition of the system of automatic control plunger lift. The using limits of the technology were given and the performance model was explained emphatically. Using proper performance model, the system of automatic control was accomplished by putting the lift project into control equipment, so the plunger lift effect was promoted. Compared with others artificial lift method, the system can validly remove wax, formation salt and scale in oil tubing with lower equipment investment and lower operation cost.
