At present, adaptive inflow control (AICD) water-controlled completion technology is mainly applied to reservoir water control. In view of the gas reservoir AICD water control completion technology research is still blank, this paper carried out a suitable for gas reservoir water control water control mechanism of the new type runner AICD and flow characteristics analysis, X oilfield bottom water reservoir is established new port type AICD water control completion. The structure parameter combination of the new AICD was analyzed and optimized by orthogonal test, and the water control effect of the new AICD water control completion was analyzed. The results show that compared with conventional perforation completions, the new AICD controlled water completions cause little bottom hole pressure loss and have little effect on condensate production. New type runner AICD completion can prolong the bottom water reservoir water control in low yielding water gas recovery period of about 365 days, predict 20 years of accumulated water rate reduced about 27%, water saturation near wellbore area is generally lower, has good effect of water control. The new flow channel type AICD controlled water completion can be applied to the development of bottom water gas reservoirs to control water and stabilize gas.
