Abstract： To addressthe underperformance of jet pump deliquification in high water cut tight gas reservoirs of Qingshimaofield，optimizing thejet pumpdeliquification technologyof high water-cut tight gas reservoirs is imperative.Inthe paper，based on the overal production characteristics and well condition parameters of gas wells in he Qingshimao field，considering the technical characteristics of jet pumpdeliquification technology under the action of waterand natural gas，combined with numerical analysis and test，the internal flow fieldof jet pump was analyzed.Then，takingWell Li- δX as an example，the characteristics of two jet pump deliquification technologies were analyzed，and the jet pump deliquification technology for high water-cut tight gas reservoirs was optimized.The study results show thatthe liquid-gas alternating jet pump deliquification technology adopts short-cycle alternating operations.This approach incorporates the advantage of hydraulic jet pump deliquification technology such as strong liquid-carrying capacity，enabling rapid gas wellrestoration. Meanwhile，it combines the advantage of pneumatic jet pumpdeliquification technology such as unafected by liquid column backpressure in the gas wellproduction，allowing the restored wellto transition directly to flowproduction.The liquid-gas alternating jet pump deliquification technology increases gas production by 20% compared to the hydraulic （water） jet pump deliquification technology，and increases liquid production by 11% and reduces composite cost by 32% compared to the pneumatic （natural gas） jet pump deliquification technology.The study results provide experimental basis and theoretical reference for the optimization of jet pumpdeliquification technology for high water-cut tight gas reservoirs.
