    Abstract:

    At the beginning of the 21st century, shaft drilling rig was commonly used in China and China manufactured wire-line core drilling pipe could only satisfy the operation of drilling depth less than 1000m, which resulted in low drilling efficiency and poor coring rate in hard formations. In the past decade, with the support of a number of major national science and technology projects, the national science and technology support program, 863 plan and the special geological survey as well as some other technical projects and by the joint efforts of enterprise-university-institute, hard rock and deep well scientific drilling technology system and geological core(2000m) drilling technology system have been formed; rapid development and progress have been made in drilling (tunneling) technologies for shallow coring (sampling), new energy resources exploration and development, geological hazards investigation and prevention, directional drilling and foundation engineering construction. The drilling development direction of “new normal of China” economy is also prospected in this paper.
