Application of Drainage Gas Recovery Technology in Natural Gas Extraction
In gas field exploitation,due to the influence of mining depth,the number of water production wells is gradually increasing,and the situation of water breakthrough is becoming increasingly severe.It is necessary to apply drainage and gas production technology well to improve the recovery efficiency of gas reservoirs.Taking the production practice of an ultra deep,high temperature and high pressure gas well as an example,the basic geology of the gas field was summarized first,and then the commonly used foam drainage technology was discussed.Based on the needs of actual gas production conditions,gas lift drainage technology was proposed from the aspects of technical principles,technical advantages,and gas lift technology process design.After testing,this technology showed good drainage gas recovery effects in ultra deep,high-temperature,and high-pressure gas wells.Finally,the gas lift drainage technology was upgraded to make up for its shortcomings in management,technological process,and other aspects,achieving safe and reliable mining.
