The Block Su-54 of Sulige Gas field is approaching the early-late period of development. Reservoir pressure and production rate are increasingly declined, number of intermittent production gas wells and frequent open-shut operation increasingly climb up due to serious water cut, which could leave more potential risks in this block. Consequently, delicacy management has been applied in this block to extend production life circle of the gas wells by modifying the conventional equation for critical liquid carrying flow rate and generated a more rational gas flow rate. Moreover, a software has been developed to calculate the reasonable open-shut time. This study reduced working load of gas well management, applied delicacy management to gas wells and enhanced gas recovery.
