◊ Changqing Oilfield Completes Second All-Hydrogen Drilling Test
On April 21, Changqing Oilfield successfully completed its second hydrogen-powered drilling test at the Jing 32-40 well site. Using a 1.5 MW hydrogen power station and hydrogen trailers, the operation achieved 100% hydrogen substitution during the entire second spud phase, consuming 9.702 tons of hydrogen and replacing 36.57 tons of diesel, reducing CO₂ emissions by 124 tons. The pilot proves hydrogen’s feasibility for low-carbon drilling, with stable operation exceeding 200 hours. This marks a key milestone in the field’s green transformation, supported by joint innovation in real-time sealing and drilling optimization under complex conditions.
◊ SINOPEC Jiangsu Oilfield Launches “AI+” Innovation Drive
On April 24, Sinopec’s Jiangsu Oilfield convened its first AI innovation team leadership meeting to implement national and group-level “AI+” strategies. The oilfield formed a leadership group and five AI task teams targeting smart transformation in exploration, production, operations, and scientific research. Key applications include intelligent seismic analysis, budget forecasting, well optimization, integrated communications, and research data management. The initiative aims to enhance efficiency, cut costs, and build smart oilfield infrastructure. Leaders stressed aligning data, talent, and real-world outcomes to drive AI-powered productivity and green development.
◊ Changqing Drills Nation’s First 2500m CBM Horizontal Well
On April 23, Changqing Oilfield completed China’s first 2500-meter ultra-long horizontal coalbed methane (CBM) well, setting three national records for horizontal section length, single-run drilling, and open-hole length. This marks a major breakthrough in CBM development under complex geological conditions. As the leading developer in the Ordos Basin, Changqing overcame technical challenges like weak structures and borehole instability through integrated geologic-engineering optimization. The project applied proprietary technologies, high-efficiency drilling methods, and customized cementing solutions, boosting drilling safety and efficiency. So far, 50 horizontal wells have been drilled, producing over 190 million cubic meters of gas.
◊ Inner Mongolia Seeks Major CBM Innovation Proposals
On April 24, the Science and Technology Department of Inner Mongolia issued a notice soliciting major innovation demands for coalbed methane (CBM) development and utilization. The initiative aims to align with regional resource conditions and support breakthroughs that enable industrial application, strengthening the region’s role as a national energy base. Relevant institutions, including universities and enterprises, must submit proposals through designated authorities by May 9, 2025. Submissions must include a sealed summary form and a Word version of the demand document. Contact details and templates are provided to facilitate participation.
◊ Baoshi Develops China’s First Titanium Alloy Coiled Tubing
Baoshi Pipe has successfully trial-produced China National Petroleum Corporation’s first titanium alloy coiled tubing, marking a major breakthrough in high-end energy pipe technology. Designed for harsh environments like deep-sea and ultra-deep wells, the tubing features high strength, light weight (43% lighter than steel), superior corrosion resistance, and fatigue resistance. It is suitable for long-term use in highly corrosive conditions such as hydrogen sulfide and carbon dioxide-rich fields. The project team overcame key technical challenges in cold forming, laser welding, and protective annealing, ensuring the tubing meets performance demands across drilling, completion, and oil-gas transport.
