介绍了适用于机采井细分找水、堵水的可调层机械堵水工艺技术。该技术主要包括液压调层和机械调层两大类管柱结构 ,其调层原理是在井口经油套环空施加液压或下入开关工具 (由电缆或钢丝携带 )完成井下各层段滑套开关的打开或关闭动作 ,进而实现相应层段的生产或封堵及堵层的反复调整 ,简化了常规找水、堵水施工工艺 ,有效解决了因选层失误造成的堵水失败问题
This paper introduces the adjustable layer mechanical water-blocking technology which is suitable for the sub-division of machine production wells to find water and block water. The technology mainly includes two types of hydraulic and mechanical transfer layer pipe string structure, the transfer layer principle is applied in the wellhead by the oil ring annulus hydraulic or under the switch tool (carried by the cable or wire) to complete the underground section of the slip Set of switches to open or close the action, so as to achieve the corresponding production or block interval and plug layer repeatedly adjusted to simplify the conventional water, water shutoff construction process, an effective solution to the failure due to failure of the election layer
