摘要
Wire-line coring and percussive rotary drilling tool is a new technology combined the advantages of wire-line and percussive rotary technology. It has obvious effect in improving drilling efficiency and construction quality. By the application test, the key technical problems affected the combination application were found: floating of inner assembly and damping effect of original inner assembly. The effective solving methods were adopted, which could be the reference for future development of this technology.
