| Abstract:In the deep drilling construction of ZK96-5 which is the first deep drilling of rock gold exploration in China, SYZX wire-line coring hydraulic hammer was used with its advantages to increase the footage per round, improve drilling efficiency and prolong bit service life in the complex broken formation; and improve drilling speed and reduce auxiliary time in the complete formation. The newest record is created with the present hole depth of 3911.34m. The paper analyzes and sums up the advantages and common problems of wire-line coring hydraulic hammer in deep drilling. |
