在金刚石钻进过程中，金刚石钻头的消耗占钻探成本的很大比重。当前，不少局、队严格注意了钻进规程，钻头平均寿命明显提高，每米金刚石消耗显著下降，其中以湖北省地质局效果最为显著，1977年全省钻头寿命平均为42米。本文对湖北三队上百个钻头的磨损进行了分析，就非正常磨损与变形找了原因，这对各使用单位改进操作，提高技术，有较大启发，对钻头制造单位提高钻头质量也有参考作用，故特发表此文，供有关单位参考。
During diamond drilling, diamond bits consume a large proportion of the cost of drilling. At present, quite a few bureaus and teams have paid close attention to drilling regulations, the average life expectancy of drill bits has been significantly raised, and the diamond consumption per meter has dropped significantly. Among them, the most significant result is from the Bureau of Geology in Hubei Province. In 1977, the average drill life in the province was 42 meters. This article analyzes the wear and tear of hundreds of drill bits in Hubei Tri-team, and finds out the reason for the abnormal wear and deformation. This has great enlightenment for improving the operation and improving the technology of each using unit, and also for improving the bit quality of the bit manufacturing unit Function, so special published this article, for the relevant units for reference.
