摘要
针对超深气井排水采气工艺技术尚未成熟、配套的状况,从川东北河坝区块产水气井开采特征分析入手,研究了气井气水同采阶段的临界携液产量、合理生产压差和合理采水规模。通过确定合理采水规模,对河坝区块HB1、HB2井实施了控水采气工艺技术,两口井均取得良好控水采气效果和经济效益。
As the technology of the water drainage gas production in super deep gas reservoir hasn't reached maturity,the paper, starting with the production characteristics analysis of water producing gas wells,makes a research on gas-water production in gas wells of Heba block.Through the analysis of critical liguid-carrying rate,of the resonable drawdown pressure and proper water production scale,the water controlled gas production technology in HB1 and HB2 has been applied,which achieved good water controlled gas production effect and economic benefits.
