摘　　要：汇集室气举是一种间歇式气举。其原理是注入气 ,首先与井液段塞接触 ,并可在注入气进入排液管下端前 ,将井液排入汇集室上方的油管并举升到地表。地层气的产出会降低其采油效率。在其旁通封隔器的汇集室顶部之间增设一个单流阀 ,将汇集室内的游离气排入其上方油管 ,就可使汇集室完全被井液充满 ,大幅度改善气举井的生产。The chamber-life is a discontinous gas-lift.The injected gas contacts with cork of well liquid first,and then the well fluid was drained into the tubing above the chamber and lifted on the surface before injected gas entering in low end of drain pipe.The formation gas reduces gas-lift efficiency.A check valve is added between by pass packer and top of the chamber to drain the free gas into the tubing above.As a result the chamber was filled with well fluid,and the production of the gas-lift well was improved.
