柔杆钻机是一种新型的钻探设备。它包括以环链牵引器为主体的地面设备,柔杆及贮存装置,钻探电机等三大部分(见附图1)。这种钻机是用电动机作为井底动力直接带动钻头旋转切削岩石和克取岩芯。用连续的柔性钻杆(简称柔杆)代替普通的刚性钻杆,由若干液压夹持器组成的环链牵引器夹持柔杆实现连续起下钻。 Flexible rod drilling rig is a new type of drilling equipment. It consists of three parts: surface equipment with chain tractor as the main body, flexible rod and storage device, drilling motor, etc. (see Figure 1). This kind of drilling rig uses the motor as the bottom hole power to directly drive the bit to rotate to cut rock and pick up the core. Continuous flexible drill pipe (referred to as the soft rod) instead of the ordinary rigid drill pipe, composed of a number of hydraulic retainer composed of chain tractor holding the soft rod to achieve continuous drilling.
