Thinking and Practice of Installation and Disassembly Tools Mechanization in Deep Coring Drilling
Abstract:Based on the analysis on current problems in the restriction of rod trip efficiency by rod installation and disassembly tools in geological drilling, the development and technical points of installation and disassembly tools mechanization were put forward, which was fit for deep coring drilling. The paper introduced the technical features and effects of the special hydraulic clamp of SQ114/8 wire line coring drilling rod.
