钻井利器的故事之"液动潜孔锤"
The story of a drilling weapon:Hydraulic DTH hammer
摘要
Abstract
Among various drilling methods,hydraulic impact rotary drilling is characterized by its high efficiency,good quality,long cycle times,few accidents,and low costs.The hydraulic down-hole hammer is the technological core of hydraulic impact rotary drilling.This article organizes the structural features of various hydraulic down-hole hammers and explores the various drilling tools which derived from the combination of hydraulic down-hole hammers,wireline coring and downhole motor drilling tools.The typical application cases of this technology are briefly introduced,and the the future development direction and technical challenges are also summarized in order to popularizing the application and promoting the advancement of hydraulic impact rotary drilling technology.关键词
