在水平钻探作业中,拧卸钻杆和拉回空载提引器是劳动强度大的工作,为了改变这种状况,我们进行了用田6钢绳带动提引器的试验。利用XU600钻机绞轮作动力,经井口架二组四只φ50～75滑轮改变方向,沿井口直至天车架一φ100～150滑轮,钢绳两端插头后,在绞轮上绕3～4圈,巡回钢绳比孔口高40厘米,用调节螺杆绷紧钢绳,开动卷扬机,转动绞轮,使钢绳巡回不停地运转(图1),带动空载提引
In horizontal drilling operations, unscrewing the drill pipe and pulling back the no-load lift is a labor-intensive work. In order to change this situation, we conducted a test to drive the lift with the Tian 6 steel rope. The XU600 drilling machine is used as a driving force, and four sets of φ50 ~ 75 pulleys of the two sets of wellhead cranes are used to change directions. A φ100 ~ 150 pulley is arranged along the wellhead till the frame of the crane. After the two ends of the steel cord are plugged, The ropes are 40cm higher than the openings. The steel ropes are tightened with adjusting screws, the hoist is started and the winch is turned so that the ropes run endlessly (Figure 1)
