Wire-line drilling is widely used due to its high drilling efficiency; however, it cannot carry out directional drilling. The wire-line directional drilling and coring technology can take cores and drill directionally without using down-hole motors. The technology is a high-tech emerging in recent years, only a few countries have mastered it, and Norway and America lead the position in the world. This paper describes the wire-line directional drilling and coring principle and technical specifications with field application in Huaze mine of Yunnan.
