Abstract: The research and development project of deep-well drilling, logging and testing technology and equipment (the second phase) is focused on the bottlenecks of key deep-well drilling technology. Based on the research efforts during the 12th Five-year Plan Period, nine important results have been achieved in this area, such as fine controlled pressure drilling equipment and technology, key technology for foothill complicated stratigraphical ultra-deep well drilling, high-efficiency rock-breaking technology represented by gas drilling, deep-well drilling fluid technology used under complicated geological conditions, rotary steering drilling system, and drilling engineering design and analysis software. These results solve part of the technological bottlenecks in the areas of China’s deep-well drilling and completion services, making China’s 7000-meter drilling technology basically mature and bringing about a breakthrough in 8000-meter drilling technology. They have significantly improved China’s deep-well drilling and completion technology.
