As of May 12th, the largest deep coalbed methane gas production base in China - the Dagiji Gas Field of China National Petroleum Corporation - has been reporting a series of successful production achievements. This year, the cumulative gas production has reached 1.412 billion cubic meters, an increase of 38.6% compared to the previous year. Currently, the daily gas output of this gas field is 11 million cubic meters, and the production trend is continuing to improve, demonstrating the practical effectiveness of the coalbed methane company of China National Petroleum Corporation in breaking through and overcoming the difficulties of deep-level extraction through technological innovation.
The Da Ji gas field has accelerated the iteration and upgrading of the lifting technology, innovatively applying new technologies such as post-segment fracturing wellbore cleaning and hydraulic rodless pumps. This has successfully overcome the traditional production bottlenecks and achieved multiple benefits including improved development, reduced energy consumption, and increased efficiency. The company's first gas well with a horizontal section over 3,000 meters - Ji Shen 8-3 Ping 01 well - has successfully completed the "wellbore cleaning" operation after fracturing, achieving a breakthrough in the key technology for cleaning the ultra-long horizontal section wellbore. At the same time, the company is accelerating the construction of intelligent well sites, intelligent pipelines, and intelligent stations, promoting the integration and application of data from multiple specialties such as geology, engineering, production, and safety, providing strong support for collaborative research analysis and intelligent production decision-making.
