摘要: 冲击回转钻井技术是钻进硬岩层的有效方法,冲击锤将冲击载荷作用于钻头和钻柱上,以
促进对岩石的破碎作用.从冲击作用的基本理论出发,对冲击器对钻头和钻柱的作用过程进行了
分析,建立其动力学模型,找出了影响冲击器性能的主要参数并推导出相应的计算公式.

Abstract: The hydro-hammer bit drilling is an effective method of drilling hard rock. The hydro-hammer exerts impact load on bit and drill string, which does good to rock disintegration. The dynamic mathematical model is established through the detailed theoretical analysis of the operating process of the hydro-hammer, and formulae for calculatin parameters of the hydro-hammer are presented.

Key words: Percussive drilling, Bottomhole assembly, Drilling tool, Energy, Parameter
