我国深层煤层气开发取得重要突破。中石油宣布我国首个成功开发的深层煤岩气田——中石油鄂东大吉气田煤岩气累计产量突破30亿方。作为首批国家级煤层气勘探开发示范项目，该气田2024年产量显著上涨，单年度煤岩气产量达16.9亿立方米，同比增长了79.2%。
大吉气田位于鄂尔多斯盆地东缘，煤岩气资源量估算约6000亿立方米，先导性实验项目于2019年开始建设。首口煤岩气实验直井大吉3-7向2井在8号煤层获得工业气流，单井产量是浅层煤层气井的5到10倍。2021年12月，大规模压裂的吉深6-7平01井在经过返排后，测试产量达到10.1万立方米，成为全世界首口煤岩气的突破井，为煤岩气商业成功开发奠定了基础。
区别于浅层煤层气以吸附气为主，煤岩气中游离气与吸附气并存，在压裂返排后可快速高产。煤岩气广泛分布于我国鄂尔多斯、四川、准噶尔等含煤盆地，资源量十分丰富，预计超40万亿立方米。业内专家认为，从开发效果看，继致密气、页岩气之后，深层煤岩气将成为我国最现实的后续天然气上产接替资源。
近年来，煤层气开发技术的进步，包括水平井钻探、压裂技术和智能排采系统的应用，提高了煤层气的开采效率和经济效益。特别是深层煤层气勘探开发理论和技术的重大突破，为煤层气产业提供了新的增长点。
未来煤层气具有广阔的发展前景，将呈现“技术驱动、政策引导、多能互补、低碳融合”的特点，在能源安全和碳中和双重目标下，其战略地位将进一步提升。
