PETROCHINA(SH:601857) Xin Hua Wang·2026-01-16 11:38Core Viewpoint - The Dagang Oilfield gas storage facilities play a crucial role in ensuring natural gas supply during winter in the Beijing-Tianjin-Hebei region, achieving a daily gas extraction rate of 25 million cubic meters, which is a 5% increase compared to the same period in 2025, with digital technology being a key factor [1][3]. Group 1 - The Dagang Oilfield gas storage cluster includes multiple underground gas storage facilities such as Dazhangtuo, Bannan, and Lujuhe, serving as essential infrastructure for natural gas supply in the Beijing-Tianjin-Hebei region [1]. - A tailored strategy of "one storage, one policy; one well, one method" has been implemented to maximize the output of key wells, ensuring reliable natural gas supply for the local population [3]. - The first digital command center for gas storage has started operation this winter, integrating real-time data from over 3,000 parameters across six stations, significantly improving operational efficiency [3]. Group 2 - The construction of additional gas storage facilities, such as Banshen 37, is accelerating, with expectations that by the end of the 14th Five-Year Plan, the gas storage cluster will achieve a working gas volume of 5 billion cubic meters per extraction cycle [5]. - Dagang Oilfield aims to enhance its digital capabilities to provide robust energy support for the green and low-carbon transition in the Beijing-Tianjin-Hebei region [5].
