摘　　要：针对辽河油区高升油田稠油气顶气窜严重影响泵效的问题，进行了长冲程稠油防气泵及其系列化研究，改变了传统的游动凡尔系统结构，扩大了其流道面积。经现场应用２３井次，取得了单井增油５．０６ｔ／ｄ，提高泵效８．９３个百分点的增产效果。In view of pump efficiency was gravely influenced by gassed out in gas cap of heavy oil in Gaosheng oilfield of Liaohe oil zone,a series study had been done on heavy oil gas prevention pump with long stroke.The new design changes traditional structure of travelling valve system,and enlarges the area of runner.When field applying in 23 wells ,oil production in single well increased 5.06 t/d,and pump efficiency increased 8.93%.
