en.Wedoany.com Reported - Wedoany News, As of May 20, the continental wells at the Zhongyuan Oilfield Puguang Gas Field have cumulatively produced 305 million cubic meters of natural gas, with daily gas production maintained above 600,000 cubic meters, an increase of 140% compared to the beginning of the year. This has become a key support for the succession of marine resources, further consolidating the foundation for stable production at the gas field。
In recent years, facing the challenge of increasing difficulty in developing marine resources, the Puguang Branch of Zhongyuan Oilfield has proactively adjusted its development strategy and continuously deepened its efforts in the unconventional continental sector. The technical team focused on development challenges of continental gas reservoirs such as "low porosity, low permeability, and high condensate oil content," as well as production pain points like liquid loading and wax blockage, successfully establishing an integrated prevention and control technical system for "wellbore liquid loading + wax blockage." At the management level, the team innovatively implemented a three-step refined management approach of "dynamic monitoring, real-time analysis, and precise policy implementation": leveraging a digital platform for dynamic tracking of key production parameters, conducting precise analysis based on changes in gas well production parameters and wellbore pressure gradient test results, and establishing a graded early warning and "one well, one policy" rapid response mechanism。
Taking Well PuLu 301H as an example, after the well transitioned to intermittent production due to severe liquid loading, the technical team monitored data in real-time. Through multiple rounds of comparative analysis, they tailored a truck-mounted compressor gas lift plan for it, restoring the well's operating time rate to 100% and increasing daily gas production by 10,000 cubic meters。
While tackling existing production challenges, the team continued to deeply explore the resource potential of long-term shut-in wells. For the three long-term shut-in wells PuLu 3, PuLu 3-1, and PuLu 3-2, technical personnel broke through the limitations of conventional single processes and innovatively implemented a combined process of "wellbore hot washing + liquid nitrogen gas lift + blowout," successfully bringing the three long-term shut-in wells back into production, adding a total of 45,000 cubic meters of natural gas per day。
In terms of expanding new blocks, Puguang Gas Field continues to increase its continental exploration efforts. In February this year, the dedicated exploration well Fen 401X was successfully put into production, with an average daily natural gas output exceeding 100,000 cubic meters. Since the beginning of this year, Puguang Gas Field has put a total of 5 new continental wells into production, with a combined daily new production capacity reaching 350,000 cubic meters. Currently, Puguang Gas Field has 23 continental wells in stable production。
