典型的油井堵水工艺在井眼或储层中应用机械或化学的方法隔离水层,可通过储层和生产数据的评估确定堵水候选井,采用挠性油管测井确定出水点并设计充填、隔离液配比及需要的隔离液的体积。2005—2010年,沙特阿拉伯南部出水油井多次尝试使用膨胀式分隔器,同时部署挠性油管作为水泥承转器或桥状沙堵来机械隔离不需要的层段。但在过度椭圆变形或冲刷的裸眼井放置分隔器时,常出现分隔器的膨胀能力不足,无法充分隔离。准确
A typical oil well water plugging process uses mechanical or chemical methods to isolate the water layer in the wellbore or reservoir. The water plugging wells can be identified by reservoir and production data assessment, flexible tubing tubing can be used to identify water outlets and design fill , The amount of spacer solution and the volume of spacer solution required. From 2005 to 2010, several attempts were made to use inflatable dividers in the effluent wells in southern Saudi Arabia while flexible tubing was deployed as a cement spinner or bridging sand block to mechanically isolate unwanted intervals. However, in the oval deformation or erosion over the open hole placed divider, often appear inadequate expansion capacity of the divider, can not be fully isolated. accurate
