油井堵水是控制油井含水上升、改善水驱效果、提高采出程度的最有效措施之一。本文针对如何提高机械堵水井施工成功率的问题,提出影响堵水井堵水成功的因素:重堵井打捞丢手接头是否能捞得上,拔堵管柱时管柱是否上窜,高液量井选择自验封封隔器等方面,对堵水成功率进行分析,并且提出解决问题的具体方法。
Oil well plugging is one of the most effective measures to control the oil well water rise, improve the water flooding effect and increase the recovery degree. In this paper, aiming at the problem of how to improve the success rate of mechanical water blocking well construction, this paper puts forward the factors that affect the water blocking success of the water blocking well: whether it can catch the lost coupling of heavy plugging well, We chose the self-sealing packer and other aspects, analyzed the success rate of water blockage, and put forward specific methods to solve the problem.
