摘　　要：针对目前中原濮城油田小泵深抽井活塞上阀罩断脱较多的现象 ,在认真分析普通上阀罩断脱原因的基础上 ,进行了阀罩改进 ,不仅出油面积增加 ,而且承载面积明显增加。通过现场 175井次的使用 ,阀罩断脱现象得到有效控制 ,平均泵效提高了 3.6 % ,因此 。In order to prevent the topside valve house of the plunger from breaking and increase the pumping efficiency,this paper analysed the texture and material of the original and find its failure.Then we designed this new type topside valve house of pump plunger by optimizating the texture and material.Having been used in over 175 wells,it was concluded that the modified topside valve house of the plunger is high efficiency,not break,high suitability and the pumping efficiency is improved.
