Feasibility study of swash plate plunger pump system in drainage gas recovery process

Abstract

Abstract With the continuous development of Sulige gas field, the formation pressure has gradually dropped, problems that liquid loading and water flooding affects the normal production of gas wells have gradually appeared. Drainage gas recovery delays the decline of gas field production to some extent, but the stable production of gas wells with large water production has become a field problem. Therefore, the pneumatic swash plate plunger pump system that does not need external power equipment but has large displacement and is easy to manage is studied. It has become another weapon to prolong the blowout period of gas wells.
