摘　　要：针对辽河油田蒸汽吞吐油井存在气锁、出砂、后期油稠泵效降低的状况 ,研制了强启闭柱塞抽油泵。这种抽油泵柱塞游动阀采用机械强制开启和关闭的结构 ,柱塞为等径光管、浮动结构 ,可防止发生气锁游动阀、阀球关闭滞后、砂卡柱塞现象。强启闭柱塞抽油泵在锦州采油厂作业四区采油现场成功应用并批量推广 ,获得了良好效果 。A forced-closing-and-opening plunger pump is developed to solve the problems of gas lock and sand inflow and low pump efficiency in steam injection wells. The travelling valve of the pump is designed to be closed and opened forcibly, and the pump plunger adopts equal-diameter bare pipe with a floating structure to prevent gas lock and sand sticking. The pump was used in Jinzhou Oil Production Plant, and good effect has been achieved.
