By improving downhole tools such as locker and constantly optimizing plunger lift system, automation of gas well came true. Production of gas well was steadier. Replacing the traditional foam carrier technology, drainage gas recovery had more obvious effects. This technology explored a new way for the development of drainage gas recovery technology of sour-gas-water wells.
