摘　　要：在深部探测和科学钻探的施工中,钻头的合理选择和使用是提高深孔硬、脆、碎岩层钻探生产效率的最重要因素之一。针对金川科学钻探深部钻进中的特殊地层岩石进行分析,利用扫描电镜研究钻头中金刚石的分布、包镶和出刃,找出合适的钻头胎体材料和金刚石工艺参数,延长钻头寿命,提高钻探效率。In the construction of deep exploration and scientific drilling, the reasonable selection and using of drill bit is one of key factors to improve the deep-hole drilling efficiency in the hard, brittle, crushed rock. Based on the analysis on the special rocks in Jinchuan scientific drilling and study on the distribution, holding and exposure of diamond in the bit by scanning electron microscope, the appropriate matrix materials for bit and diamond process parameters are found to prolong the service life of the diamond bit and improve the drilling efficiency.
