Chinese Abstract

针对胜利油田中后期开发中油层含水大幅上升、层间矛盾加剧和作业成本居高不下等问题,开发了不动管柱换层开采工艺,不动管柱液控循环换层开关是该技术的关键所在。介绍了该井下开关的结构原理、技术特点及现场应用情况。该工具与封隔器等工具组合,可任意控制各油层的生产或关闭。不动管柱液控循环换层开关的应用提高了换层采油效率,简化了分层找水和采油措施。改进后的换层开关在现场共施工21井次,只有1井次因砂埋管柱使换层作业失败,施工成功率95.3%,比改进前提高15.3%。

English Abstract

The selective zonal withdrawal technology is used in Shengli Oilfield since the water cut of the oilfield is becoming higher and higher. The hydraulic cyclic layer-shifting switch is the key technique of this production technology. The design feature, technical characteristics and field application of this new down hole switch are introduced. Used with packers, the switch can control the opening and closing of every production zone conveniently. Therefore the utilization of the switch improves the efficiency of zonal production, and simplifies the zonal water detection and oil production procedures. Field use shows this down hole switch has reliable performance.
