In the Sebei-2 gas field, the number of water wells in the Sebei loose sandstone edge water gas reservoir increases year by year, therefore continuous drainage is required to maintain production. At the same time, due to the serious sand production in the gas wells, the application of artificial lift technologies such as rod pumps and electric pumps is fairly limited. In response to this problem, according to the surface conditions of distribution density of gas wells, incorporating the existing surface production process and gas well production dynamics, the research on gas lift method, gas lift parameters, compressor selection, hydrate inhibition and gas injection processes has been carried out. The process of using motor-driven reciprocating compressors for boosting wet gas, gas distribution at gathering stations, and multi-well gas lift gas injection was developed. This research also makes full use of the residual heat of the booster gas for injection as heat insulation of the trunk line and for injection into valve manifold area for hydrate inhibition and into casing annulus to enhance tubing oil production; and develops the multi-well centralized gas lift drainage gas extraction process and gas lift valve combined lifting method. By the end of 2020, it has completed the associated facilities project which can meet the gas lift of 83 gas wells at the same time;70 continuous gas lift drainage wells have been implemented, and has produced 122 million m3 of additional natural gas. As the impact is significant, this research can be used as an important reference for managing water of water-gas reservoirs.
