摘　　要：组合钻探工艺是一种为了提高不同地层取样钻探施工综合效率的多用途钻探技术。该工艺方法将当今地质找矿钻探最先进和广泛应用的反循环连续取心 (样 )及金刚石绳索取心钻探技术有机地结合起来 ,利用一套器具 ,可实现多种工艺方法 ,并针对地层、施工环境及地质要求 ,采取与之相适应的钻探方法 ,达到优质高效的综合钻探目的。介绍了组合钻探工艺的研究与应用试验过程及取得的技术效果。Combined drilling technology is a multi purpose drilling method which is developed to increase the comprehensive drilling efficiency in different formations. It combines the RC drilling with the diamond wireline coring drilling and uses the same drilling pipes and tools to realize several drilling methods adapted to its formations according to the engineering environments and geological requirements and so on. The processes of the combined drilling technology research, field testing and technical effects are described in the paper.
