Abstract: The 10 000-meter ultra-deep well drilling and logging technologies are crucial for deep oil and gas exploration and serves as a key indicator of a nation’s strength in energy exploration and development. Through the implementation of ultra-deep well drilling projects exemplified by Well Shenditake 1, China has preliminarily established an ultra-well drilling and logging technology system with distinctive Chinese characteristics. Critical drilling technologies, such as 15 000-meter automated drilling rigs, Grade V150 high-strength drill pipes, and high-performance water-based drilling fluids resistant to 240 ℃ have been successfully developed, ensuring safe and efficient drilling operations. Logging tools,including a 230 ℃ and 180 MPa slim-hole imaging logging tool, a supporting ground acquisition and processing platform, and communication cables suitable for depths exceeding 10 000 meter,have been successfully developed, facilitating the acquisition of geological engineering data from 10 000-meter-deep formations. Despite the significant breakthroughs achieved in China’s 10 000-meter-deep drilling engineering technology, gaps persist relative to the top international standards. Key areas requiring further improvement include the long-term reliability of downhole tools and instruments, service life under high temperature and pressure conditions, long-range imaging accuracy, and advanced materials. Looking forward, 10 000-meter-deep well drilling and logging technology will continue to evolve toward greater depth, higher intelligence, greater efficiency, and enhanced safety. Key technological breakthroughs remain essential, particularly in materials with high temperature resistance exceeding 260 ℃, intelligent autonomous decision-making systems, high-efficiency rock-breaking tools, extreme high-temperature and high-pressure downhole imaging technologies, and intelligent quantitative interpretation systems. Through profound cross-disciplinary integration and ongoing iterative innovation, these advancements will provide robust technical support for the large-scale exploration and economically efficient development of deep oil and gas resources.
