| 摘 要： | 针对中深斜孔钻进中φ60mm绳索取心钻杆机械强度低、耐磨性能差、钻杆拧卸难等问题，采用对绳索取心钻杆整体调质处理的方式．大幅提高了绳索取心钻杆的机械强度；对绳索取心钻杆表面高频淬火，提高了钻杆表面的硬度和耐磨性；采用重型绳索取心带切口接手，初步解决了绳索取心钻杆拧卸问题。采用上述钻杆在中深斜孔钻进中取得了较好的效果。

| Abstract: | Disadvantages of φ60mm wire-line coring drilling rod in medium-deep inclined hole drilling include： low mechanical strength, poor wear-resistance and inconvenient drilling rod disassembling. Quenching and tempering treatment was adopted to wire-line coring drilling rod, the mechanical strength was greatly improved; high-frequency quenching was made to the surface of drilling rod, the hardness and wear-resistance were increased ; and the difficulty of disassembling for wire-line coring drilling rod was preliminary solved by heavy wire-line coring joint with mill groove. |
