en.Wedoany.com Reported - As of May 12, China's largest deep coalbed methane production base—PetroChina's Daji Gas Field—has reported frequent production successes, with cumulative gas production this year reaching 1.412 billion cubic meters, a year-on-year increase of 38.6%. Currently, the gas field's daily gas output stands at 11 million cubic meters, with production momentum continuing to improve. PetroChina Coalbed Methane Company Limited has achieved new results by leveraging technological innovation to break through bottlenecks and overcome difficulties in deep-layer extraction.

The Daji Gas Field has accelerated the iterative upgrading of its artificial lift technologies, innovatively applying new techniques such as post-fracturing wellbore cleaning in horizontal sections and hydraulic rodless pumps. These advancements have successfully overcome traditional extraction bottlenecks, achieving multiple benefits including enhanced development quality, reduced energy consumption, and improved efficiency. The company's first gas well with a horizontal section exceeding 3,000 meters, the Jishen 8-3 Ping 01 well, has successfully completed post-fracturing "wellbore plug sweeping" operations, marking a breakthrough in key technologies for cleaning ultra-long horizontal wellbores. Meanwhile, the company is accelerating the construction of platforms such as intelligent well pads, intelligent pipelines, and intelligent stations, promoting the integrated application of multi-disciplinary data including geology, engineering, production, and safety, thereby providing strong support for collaborative scientific research analysis and intelligent production decision-making.
