The research and application of water controlled gas production technology in super deep gas reservoir in Northeastern Sichuan Heba block

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.
