Application Research on Liner Tube without Variable Diameter of Shale Gas Plunger Gas Lift Wellhead

Given that there is variable diameter in the shale gas plunger lift wellhead, which causes cannot run up and down well affects effect of drainage production, paper carries out research on liner tube without wellhead installation methods, makes consistent with oil pipe, ensure can be open Christmas tree, facilitate periodic inspection replacement operation plunger, reduces cost salvage operations. The successful application process plan ** has achieved good production effect, truly solved problem goal once for all.
