Yang Shi Wang·2026-01-03 23:16Core Viewpoint - China's largest oil and gas field, Changqing Oilfield, is projected to achieve an annual natural gas production of 51.42 billion cubic meters by 2025, maintaining a steady output above 50 billion cubic meters for four consecutive years, which is expected to account for one-fifth of the country's total natural gas production [1]. Group 1 - Changqing Oilfield, located in the Ordos Basin, will implement measures to address declining production from old wells and decreasing formation pressure by conducting 14,000 well interventions, which are expected to increase natural gas output by 2.6 billion cubic meters [3]. - The field will also see the commissioning of over 1,900 new gas wells, contributing more than 2.8 billion cubic meters of natural gas in the same year [3]. Group 2 - Over its 30-plus years of development, Changqing Oilfield has successfully developed 15 gas fields, including Jingbian, Yulin, and Sulige [5]. - Since it began supplying gas to Beijing in 1997, the oilfield has produced over 700 billion cubic meters of gas, equivalent to replacing more than 90 million tons of standard coal and reducing carbon dioxide emissions by over 1 billion tons [5].
