摘要
详细分析金刚石钻头在施钻时出现打滑原因的基础上，指出了克服打滑的各种措施的优缺点。经反复试验后，研制出了一种新型钻头，在同样工艺条件下，钻头的平均钻进效率从每小时0.25m提高到了1.08m，具有显著的经济效益。
Based on the analysis of slipping causes of diamond bit while drilling,the paper discussed the merits and defects of various antislipping measures. After repeat tests,a novel antislipping diamond bit was developed. Under the same technological conditions, the average drilling rate of this bit can increase from 0. 25m/h to 1.08m/h and has significant economic benefits.
