我局已经有五年金刚石小口径钻进的经验，在此基础上，我们从1980年开始逐步试验和采用绳索取心钻进，累计进尺近万米，并且积累了一定经验。一、钻探设备及工艺技术（一）设备及钻具1．钻机：xu-600-3型钻机，其上安S56J-1型绞车，φ4.8毫米钢丝绳500～800米。2．水泵：BW250/50型泥浆泵。3．钻塔：12米（或17米）斜塔。4．钻具：S56-D绳索取心钻具打捞器。5．钻杆：钻杆的材质为45M_nM_0B，规格为φ53× Our bureau has had five years experience in drilling small diameter diamonds. Based on this, we have been gradually testing and adopting cord coring drilling since 1980, accumulating a total footage of nearly 10,000 meters and gaining some experience. First, drilling equipment and technology (A) equipment and drilling tools 1. Drilling rig: xu-600-3 drilling rig, the safety of the S56J-1 winch, φ4.8 mm wire rope 500 to 800 meters. 2. Pump: BW250 / 50 mud pump. 3. Drilling Tower: 12 meters (or 17 meters) Leaning Tower. 4. Drilling tools: S56-D rope coring drill salvage. 5.
