摘　　要：从油层出来的天然气对抽油机井产量影响的研究,大多数都集中在抽油泵部分,还没有井口气锁问题的研究。从气油比比较大的抽油机井的生产现象出发,分析了没有液体到达井口的原因,提出了井口气锁的概念,实施了井口气锁的解决办法,实施后效果好。The research of the influence about natural gas on the deliverability of pumping unit is almost focused on the sucker rod pump,while wellhead gas lock has not been researched.Based on the production performance of rod pumped wells with high gas - oil ratio,this paper analyzed the reason that the liquids can't reach the wellhead and proposed the concept of the wellhead gas locking.The solution of the wellhead gas locking was gotten and achieved good results.
