| 中文摘要:金刚石钻进是我国的一种主要钻进方法，在地质勘探和油气井钻进中得到了广泛应用。为了提高其技术经济指标，研究金刚石钻进时岩石的应力变形状态、岩石破碎过程及其与规程参数的关系很有必要。俄罗斯钻探工作者在金刚石钻进岩石破碎方面做了大量的试验研究工作，研究了钻进速度与规程参数的优化关系，提出了临界规程参数组合的概念，推荐了保证正常钻进、防止钻头非正常磨损等的措施。值得我国同行们参考。 |

| Abstract:Diamond drilling is one of the main drilling methods in China. It is applied widely in geological explotation， and oil and gas drilling. In order to improve technical and economical index of the method， research on the stress-strain state of rock to be drilled， the rock fragmentation process and its relationship with drilling parameters is very necessary. Russian drillers have done a lot of relevantwork： they studied the optimal relationship between penetration rate and drilling parameters， proposed the concept about the combination of critical drilling parameters， and recommented measures guaranteeing normal drilling and prevening abnormal wear of drill bits， etc.， which can provide some reference for the Chinese counterparts. |
