Research progress of intelligent drilling equipment and technology

For the development and utilization of complex marine and continental oil and gas resources, and some problems of heterogeneity and uncertainty inevitably encountered during the drilling under complex geological conditions, it is urgent to create opportunities for the development of intelligent drilling technology and equipment using the high-end information such as artificial intelligence, big data and machine learning. Herein, the intelligent drilling system and its basic components were described, mainly including the field surface intelligent control platform, the data measurement communication control network system, the downhole intelligent steering drilling system and the remote real-time intelligent control center system. Besides, the development status of intelligent drilling equipment at home and abroad, such as the intelligent drilling rigs, intelligent drill pipes, intelligent drill bits and intelligent drilling analysis platforms, were systematically summarized, and the intelligent development potential of the intelligent directional drilling technology, intelligent coring technology, intelligent drilling fluid technology, micro-hole drilling technology and unmanned drilling was predicted. In the context of a new round of energy revolution and industrial transformation, the accelerated integration of drilling technology and equipment with the emerging information technologies will promote the development of drilling technology and equipment in a more intelligent and unmanned direction, thereby realizing the automation of the entire drilling process. The application of intelligent drilling equipment and technology can improve the drilling efficiency and safety, reduce the impact on the environment, and further promote the development of energy revolution and industrial transformation. At the same time, an effective low-carbon development plan and implementation plan was formulated, to comprehensively promote the innovation and iterative optimization of intelligent drilling technology, equipment and supporting software, accelerate the construction of high-end intelligent platforms, and continuously improve their support and guarantee capabilities for the exploration and development. In this paper, the intelligent drilling equipment and technology was systematically discussed, so as to provide some reference and inspiration for the scientific research and technological development of intelligent geological drilling in China.
