摘要
为实现吴起油田水平井找水堵水工艺技术取得更好的应用效果,本文通过划分低产低效水平井的种类,分析其出水的原因,提出了适合吴起油田现状的水平井找水堵水工艺,即采用机械卡封+油管抽汲试油的方法找水。同时提出了根据出水位置确定桥塞封堵、封隔器隔采或水泥挤封等多种后期采油工艺技术,并对其经济效益和应用前景进行了分析,为吴起油田水平井开发和后期治理提供了新的思路和方法。
In order to achieve better application effect of water seeking and plugging technology in horizontal wells of Wuqi oilfield,this paper analyzed the causes of water discharge by dividing the types of low-yield and low-efficiency horizontal wells,and proposed to use the method of mechanical sealing and tube sucking and testing oil to seek water in horizontal wells,which is suitable for the current situation of Wuqi oilfield.At the same time,it puts forward various post-extraction technologies such as bridge plugging,packer isolation and cement extrusion,etc.Based on the location of the water outlet.It also analyzes the economic benefits and application prospects,and provides new ideas and methods for development and post-treatment of horizontal wells in Wuqi oilfield.
