摘要
本文主要介绍了空气潜孔锤在煤层气钻井中工作原理、钻具组合、主要技术参数的计算选择和钻进中的注意事项,并尝试采用三牙轮钻头进行冲击回转钻进第四系,提高整体钻进效率。
The paper mainly describes the working principles, drill assembly, computation and selection of major technical parameters and points for attention in drilling. The author made a trial to penetrate strata of the Quartemary Period by using tri-cone drill bit for rotary and percussive drilling in order to enhance the entire drilling efficiency.
