摘　　要：针对新疆油田吉7井区稠油定向井举升中存在的问题,成功研制了投捞电缆式潜油螺杆泵举升工艺。但该工艺在前期应用过程中出现联轴器断裂、动力电缆无绝缘、插接头组件对接困难等问题。经过反复分析,持续改进,采用低转速大扭矩永磁同步电动机替代传统带减速器电机,升级动力电缆和绞车的性能,有效解决了上述问题,同时研制配套的防砂控制阀,解决了停机后油管内砂子沉积在泵上端的问题,该技术整体应用效果良好,适用性更强。Aiming at the problems existing in heavy oil lifting of directional wells in Ji 7 well block of Xinjiang Oilfield, the drop-fishing cable submersible screw pump lifting technology is successfully developed. However, in the early application of this technology,there are some problems, such as coupling fracture, no insulation of power cable, difficult docking of plug-in components and so on.After repeated analysis and continuous improvement, it took 3 years to replace the traditional motor with reducer with low-speed and high-torque permanent magnet synchronous motor, and upgrade the performance of power cable and winch, which effectively solved the above problems.At the same time, the supporting sand control valve is developed to solve the problem of sand in the tubing depositing on the upper end of the pump after shutdown. The improved technology has good application effect and good applicability.
