Recently, a ultra-high-temperature drilling fluid system—built around oilfield chemicals independently developed by the Engineering Research Institute of Sinopec—was successfully applied to Well Xinyuan 22 at a depth of 11,116.00 meters, with operating temperatures exceeding 230°C. This application has helped the well set several national records, including the shortest drilling cycle for a 10,000-meter well (282.52 days) and the deepest drilling depth achieved using water-based drilling fluids. This milestone marks a significant technological breakthrough in Sinopec’s ultra-high-temperature drilling fluid technology for 10,000-meter wells, signaling that ultra-high-temperature products have moved from technological innovation to practical application and value creation.

At the start of the new year, China National Petroleum Bohai Drilling announced a major breakthrough in the Bayan market: The Guangming 5X ultra-deep exploratory well, drilled by the BHZ80002 drilling team, has successfully completed cementing operations for an ultra-deep casing string measuring 6,799.87 meters. The cement slurry flowed smoothly back to the surface in one go, with zero errors or malfunctions throughout the entire process. This milestone marks another key technological breakthrough for China in the exploration and development of ultra-deep oil and gas resources in the Hetao Basin, paving the way for the efficient exploitation of this energy-rich "deep-earth" region.
