柔杆钻机是一种新型的钻探设备,主要由钻机、柔性钻杆和井底动力钻具三大部分组成。柔杆钻机的主要原理是使用由多层弹性材料制成并具有抗拉、抗扭、抗挤和抗爆强度,能够导通电、通泥浆水,以及有一定的柔性和长度很大的连续性柔性钻杆,来代替普通的地面旋转钻机所使用的不连续刚性钻杆进行钻井;钻井时,钻杆不需转动,由井底动力钻具(钻探电机或涡轮钻具)直接在孔底驱动钻头进行钻井;起下钻时,使用双链式牵引器进行连续起下钻操作。
Flexible rod drilling rig is a new type of drilling equipment, mainly by the drilling rig, flexible drill pipe and bottom hole power drill three major components. The main principle of the flexible rod rig is the use of multi-layer elastic material and has a tensile, torsional, anti-extrusion and antiknock intensity, able to conduct electricity, through the mud water, and have a certain flexibility and length of continuous Flexible drill pipe, instead of ordinary ground rotary drilling rig used to drill a continuous rigid drill; Drilling, the drill pipe without rotation, the bottom hole power drill (drilling motor or turbine drill) directly on the bottom of the hole Drilling bit for drilling; when drilling down, double-dragger is used for continuous drilling.
