我国的金刚石钻进正在作为一种比较先进的技术加以推广。在一些地层中,特别是在坚硬地层中正在显示出它的优越性。在机械钻速、钻头进尺方面都有一定提高,每米钻进成本正在下降,取得了较大的成绩。但是在金刚石钻进中遇到的一个突出问题就是烧钻问题。据有关资料,许多钻头之所以进尺不够理想,主要原因是由于钻头烧钻所引起的。因此钻头烧钻问题正在影响着金刚石钻 China’s diamond drilling is being promoted as a more advanced technology. In some formations, especially in hard formations, it is showing its superiority. In the ROP, drill bit footage have a certain increase, drilling cost per meter is declining, and achieved great results. However, one of the outstanding problems encountered in diamond drilling is the problem of burnt diamonds. According to the relevant information, the reason why many drills are unsatisfactory is mainly due to the bit drilling. So drill bit drilling problems are affecting the diamond drill
