| Abstract:According to the practical application of China-made wire-line coring drill pipe in ZK96-5 of the first deep drilling engineering construction by China Rock Gold Exploration and combined with the actual situation of existing drilling tubing specifications and materials, heat treatment and machining precision, the analysis and the summery are made on the advantages and disadvantages of CNH（T）wire-line drill pipe with 71mm in diameter about the structure, joint, thread button shape and size. The practice proves that this China-made wire-line core drilling tool is suitable to deep drilling with high strength, long service life and high reliability. In the construction of ZK96-5, the maximum depth has reached to more than 3310 meters. |
