The ultra-deep hole geological core drilling technology and equipment is successfully developed by the Institute of Exploration Techniques， CAGS in cooperation with several domestic units.It is the research achievement of the national key R & D program “Research and Development and Demonstration of 5000m Intelligent Geological Drilling Technology and Equipment” of the “13th Five Year Plan”. The ultra-deep hole geological core drilling is standardized designed， the drilling equipment is lightweight， the drilling control is intelligentized， the wellhead operation is automatic， the in-hole drilling tools is seriation， and the mud system is greenization. The integration and demonstration application is completed taking the JZ04 geothermal geological exploration well as the demonstration platform. As a result， a new minor-caliber structure for geological drilling is rebuilt， two Asian records is created namely the deepest drilling depth using ?114mm wire-line coring technology and the deepest depth using ?146mm geological casing. The ultra-deep hole geological core drilling technology and equipment system with the wire-line coring as the main technology is preliminary formed.
