基于现有修井机的动力和提升条件，研制出一种井口无人操作起下油管装置，主要包括油管自动悬吊系统、液压钳自动上卸扣系统和远程液压控制系统。各部分的操作指令集中到修井机的控制台上，由司机手远程操控完成油管的抓放、扶正、对中、悬持、上卸扣、锁定和起下，实现了1名司机手和1名场地工即可完成起下油管作业，不仅降低了工人劳动强度，而且保证了工人起下油管时远离井口危险区域免受伤害。该装置结构简单，体积小，性能稳定，不占用井口人工操作空间，不影响人工井控抢险，不妨碍井口人员逃生，不增加搬家车辆和运行成本，施工速度可控且与人工操作水平相当，受到现场工人的欢迎。

Based on the existing power and elevating conditions of workover rig, a kind of device of pulling and running tubing string with unmanned operation at wellhead is developed. It mainly includes automatic suspension system, hydraulic pincers automati-cally screwing system and remote hydraulic control system. Control commands of each part are concentrated on workover console. A driver remotely controls to catch or put, centralize, center, hang, screw, lock, pull or run tubing. A driver and a site worker can complete the work, which not only reduces the labor intensity, but also keeps the workers away from the harm of dangerous area at wellhead. The new device has great advantages with its simple design, small volume and stable performance, do not occupy the wellhead artiifcial operation space, do not affect the artiifcial well control emergency, do not interfere with the wellhead evacuation and do not increase the moving vehicles and operation cost. Its operation speed is controllable and as nearly as manual operation. It is popular with the oilifeld workers.
