摘要
分析了大口径嵌岩钻进面临的主要技术难点，并对目前国内常用的３种大口径嵌岩钻进方法牙轮／滚刀钻进法、冲击钻进法（包括无循环和反循环）和气动／液动潜孔锤钻进法的技术现状作了介绍，提出了提高我国大口径嵌岩钻进技术水平的建议。
The main technical challenges present with large diameter rock socket drilling are analysed. The technical status quo of three conventional large diameter rock socket drilling methods, e.g. cone bit/disc cutter drilling method, percussive drilling method (no circulation and reverse circulation) and air/fluid powered DTH drilling method, is described with concrete proposals initiated for increasing the technical level of large diameter rock socket drilling.
