Keshen gas field is located in Kelasu structural belt of Kuqa depression. The main development layer is the Cretaceous Bashijiqike Formation. The edge and bottom water of the gas field are active and the development mode is exhaustion development. With the further development of Keshen gas field, the number of production wells is gradually increasing. At present, blocks KS2, KS8, KS24, etc. have seen water in succession, and the form of water breakthrough is severe. In order to delay the water invasion of the gas reservoir and improve the recovery ratio of the gas reservoir, water drainage and gas recovery is the main means of water control in the gas reservoir. Since the research on water drainage and gas recovery technology has not been carried out for ultra-deep high-temperature and high-pressure gas wells, Keshen gas field has successively carried out foam drainage, electric submersible pump drainage and pilot test for gas-lift drainage technology. The gas-lift drainage & gas recovery technology has achieved good results through its field application. Meanwhile, this technology has the characteristics of wide application, simple process, high degree of automation and easy management, etc. It provides technical means for water drainage & gas recovery in ultra-deep high-temperature and high-pressure gas wells and valuable experience for drainage & gas recovery of gas wells of the same nature.
