摘要：

国内智能井使用的常规电控式井下流量控制阀集成的井下监测系统无法监测流量与含水率两个关键参数，且存在驱动机构失效后传动丝杠自动锁紧滑套当前位置，滑套无法及时关闭或全开的问题，导致无法对控制层段或分支的产量进行调控。根据优选的压力传感器、温度传感器、含水率传感器、流量计与井下滑套位移传感器，设计独特的滑套机械结构集成井下参数测量系统，解决国内现有电控式井下流量控制阀无法监测流体流量与含水率的问题；结合可伸缩联轴器设计结构独特的机械传动系统作为同心滑套的驱动机构，且集成强开强关机械结构，可通过滑套开关工具将滑套移动至全开或全关位置，弥补了国内常规电控式井下流量控制阀机械结构上的不足，为智能井技术的迭代发展提供了关键支撑。

Abstract:

The downhole monitoring system，integrated into the conventional electric control downhole flow control valve for intelligent wells in China，cannot monitor the two key parameters，namely the flow rate and water cut. Moreover，once the driving mechanism fails，the transmission screw automatically locks the sliding sleeve at the current position，making it impossible to close or fully open the sliding sleeve in a timely manner and resulting in the inability to regulate the production of the target layer or branch. In this research，a unique sliding sleeve mechanical structure with an integrated downhole parameter measurement system was designed using the selected sensors of pressure ，temperature and water-cut，flow meter，and downhole sliding sleeve displacement sensor，to solve the incapabilities of existing electrical-control downhole flow control valves in China to monitor fluid flow and water cut. A unique mechanical transmission system was designed using the scalable coupling to serve as the driving mechanism for the concentric sliding sleeve. The designed sliding sleeve integrates a force-open force-close mechanical structure，which can be moved to the fully open or fully closed position by the sliding sleeve switch tool. This eliminates the shortcomings of the mechanical structure of conventional electric control downhole flow control valves in China and provides key support for the development of the intelligent well technology in China.
