摘要
为了进一步提高偏心注水井投捞效率和成功率,研制了可适用于偏心分层注水井的电动投捞器。基于传统机械式钢丝投捞工艺两次下井完成投、捞堵塞器动作的机械原理,利用高扭矩电动机对投入臂、捞出臂及支撑臂进行驱动,使用单片机结合多种高精度传感器,确定机电一体化结构,实现投捞功能电动化。综合机械结构和电气原理研发出了适用于偏心注水井的电动投捞器,通过电动机传输动力实现投入臂、捞出臂的开关动作,采用双导向结构设计克服了6m冲击距离的限制,内置11个传感器可以随时观察测量整个仪器的工作状态。电动投捞器现场共应用21井次,成功率达到90%以上,节省投捞时间30%,投捞时无需冲击距离,地面可以直接读取投捞臂位置和工作状态,简化了工作流程并提高了投捞成功率。电动投捞器整体应用效果良好,可大规模推广应用。
In order to further improve the running and pulling efficiency and success rate in eccentric water injection wells, the electric running and pulling tools suitable for eccentric separate layer water injection wells have been developed. Based on the mechanical principle of running and pulling the plug with twice trip by steel wire in traditional ways, the high-torque electric motors were used to drive the running arm, pulling arm and support arm,and the single chip was combined with multiple high-precision sensors into the mechanical & electrical integration structure to realize the electric functions in running and pulling operations. By using mechanical structure and electric principle, the electric running and pulling tools were manufactured for eccentric water injection wells, with the on-off action of both running arm and pulling arm driven by the power of electric motors. The design of double guide structure can overcome the restriction of 6m impact distance, and the 11 built-in sensors can observe the working state of whole instrument at any time. The electric running and pulling tools have been applied in well site for 21 well times with success rate up to 90%, saving the time of running and pulling operation by 30%, and no impact distance in the operation. The surface tools can read the position and working state of running and pulling arms directly, which will simplify the working process and improve the success rate of running and pulling operation. The overall application effect of running and pulling tools are satisfied, which can be applied and popularized in large scale.
