我局近几年来逐步推广金刚石钻探，取得了较好效果，但由于设备、工艺不配套和技术操作等原因，直接影响了钻头寿命的提高，最近对一批钻头进行分析发现，非正常磨损的比重达69.4％，连同钻头售价不合理导致钻探成本人为增高，成为金刚石钻探发展的障碍。影响钻头寿命因素很多，从金刚石质量、钻头加工方法、地层的适应性到钻进工艺和技术操作都和钻头的综合经济指标紧密相连，钻头长寿命要经过设计、加工、管理和现场操作人员的共同努力。操作中的微小疏忽，将会导致钻头的非正常磨损或损坏，所以每一回次终了，要仔细观察钻头形态变化，正确判定磨损原因，及时采取措施。
In recent years, I gradually promote the diamond drilling, and achieved good results, but due to equipment, technology does not complete and technical operation and other reasons, a direct impact on the life of the drill bit, a recent analysis of a group of drill found that abnormal wear The proportion of 69.4%, together with the unreasonable price of drill bit, has led to the increase of drilling cost, which has become an obstacle to the development of diamond drilling. There are many factors that affect the life of a drill. From diamond quality, bit processing method, formation suitability, drilling technology and technical operation, it is closely linked with the integrated economic indicators of drill bits. The long life of the bit is subject to the design, processing, management and on- Work together. Small negligence in operation will lead to abnormal wear or damage of the drill bit, so every time the end, we must carefully observe the drill shape changes, the correct determination of the causes of wear and tear, take timely measures.
