摘要
Abstract
Being dead against drilling and coring problems encountered in difficult formation, a coring tool with eccentric drilling type simultaneous casing used in difficult formation is considered by the combination of DTH drilling with simultaneous casing, local area reverse circulation process and rigid type coring tool. The design principle, design concept, operating theory and features of the drilling tool are expounded.关键词
