摘　　要：分析了在高油气比的井况条件下,抽油泵在抽汲过程中,泵内液体和气体的体积变化,以及影响抽油泵泵效的原因。提出防气泵的防气功能在于清除余隙内的游离气和尽量减少余隙液体中的溶解气。提出了一种既大幅度提高泵效、成本低廉又彻底解决了"气锁"的新型防气抽油泵,并介绍了该泵的工作原理及基本组成。At the conditions of high oil-gas ratio, the volume change of the liquid and gas, and the reasons of affect the pump efficiency of the pump during the swabbing are analyzed in this paper, and it is proposed that the function of anti-gas-pump can eliminate free gas in the clear span and reducing solution gas in the liquid of clear span as much as possible. The new anti-gas pump is proposed, which not only cost less and increase pump efficiency remarkable but also completely avoid the ＂gas locking＂, and its working principle and the basic component are introduced.
