Research and development of 5000m intelligent geological drilling technology and equipment

Abstract:

Deep drilling technology is one of the necessary means to solve the scientific and technological problems in deep exploration. This paper mainly introduces the research and development program of 5000m intelligent geological drilling technology and equipment. It starts from the conceptual design of great-deep wire-line coring drilling diameter series, drilling tool classification, and equipment configuration, and is followed by R & D of drilling intelligent control, key drilling technology and equipment, high-performance wire-line coring drill pipes, small diameter and high-efficiency series drilling tools, environmental protection drilling fluid system and waste slurry treatment technology, integration and demonstration of drilling technology and equipment, etc. The program is aimed to achieve key technological breakthrough in intelligent control, portability and modularization; and build the ultra-deep hole drilling equipment and technology system mainly with the wireline core drilling process. It will provide technical and equipment support for China’s deep exploration plan.

Key words:deep exploration; geological drilling equipment; drilling technology; ultra-deep hole; intelligent control
