| 中文摘要:我国正在进行深部地质找矿和深部矿产资源开发，“十三五”计划规定了对地下空间的利用和开发进行研究，这些都离不开深部钻探。深部钻探中遇到的岩石多为各向异性岩石，在这种岩石中钻进时，钻孔容易偏斜，影响钻探效率和质量。俄罗斯博士Скоромных В.В.教授等对此进行了研究，提出了钻头水口大小变化的设计思想。对比试验结果表明，这种新钻头钻进技术指标较好，值得研究和探讨。 |

| Abstract:Deep geological survey and exploitation of deep mineral resources are carrying out in China, and the 13th five-year plan sets the research on the exploitation and utilization of underground space, which are inseparable from deep drilling. The rocks encountered in deep drilling are mostly anisotropic ones; borehole is easy to be deflected in this condition, which affects the penetration rate and drilling quality. The related research has been carried on by Russian Professor Скоромных В.В. and some others, a new design idea of diamond bit with waterway of different sizes is proposed. The comparative experiment results show that the technical indexes of this new bit are better than the old diamond bits with standard waterway sizes, and this technology is worth while researching and discussing. |
