我国煤岩气地质资源量成数十万亿方级别“新粮仓” 开辟全球天然气增长新领域

Core Insights - A recent study from the China Petroleum Coal Rock Gas Key Laboratory indicates that China's coal rock gas geological resource potential could reach 50 trillion cubic meters, positioning it as a significant new energy source [1] - The exploration and development of coal rock gas is gaining momentum, becoming a new highlight in China's natural gas production amid the country's dual carbon goals and energy transition [1][2] Resource Potential - The Ordos Basin alone holds over 25 trillion cubic meters of coal rock gas resources, with other basins like Sichuan, Tarim, Junggar, Bohai Bay, and Turpan-Hami also showing strong resource foundations for efficient exploration and development [1] - As of October 2025, the cumulative proven geological reserves of coal rock gas in China are expected to exceed 700 billion cubic meters, with production projected to rise from 2.7 billion cubic meters in 2024 to 4 billion cubic meters in 2025 [2] Theoretical Innovations - The discovery of coal rock gas challenges traditional geological theories, which considered depths over 1500 meters as development "forbidden zones" due to lower gas adsorption and high costs [3] - The new concept of coal rock gas (Coal-rock Gas, CRG) was proposed by the China Petroleum Exploration and Development Research Institute, supported by the broader "total oil and gas system" theory, which integrates conventional and unconventional gas resources [4] Development Progress - China's coal rock gas exploration has shown rapid growth, achieving significant breakthroughs in the Ordos Basin, including the discovery of three large gas fields with geological reserves exceeding 500 billion cubic meters and the establishment of the first million-ton deep coal rock gas field [8] - By 2035, China aims to establish a production capacity of over 30 billion cubic meters of coal rock gas, with ongoing plans for multiple large-scale gas fields [8]
