摘　　要：天然气资源是能源利用由化石能源向非化石能源转型的过渡能源,煤系天然气是天然气的重要组成部分。为了充分发挥煤系天然气开发在我国“双碳”目标中的优势,对煤系天然气高效开发在能源转型中的价值作用及其发展方向进行了分析与研究。结果表明:我国煤系天然气资源类型多、资源量大且分布广泛,具有大规模高效开发的资源基础。高效开发煤系天然气资源对促进能源低碳发展具有重要意义,能够有效降低高碳化石能源消费占比,减少CH4温室气体排放,与CCUS技术结合实现增产减碳双效应。煤系天然气开发与新能源发展可实现协同促进,可以保障新型灵活电力系统的优质调峰,实现安全高效低成本制氢、利用煤系储氢,以及与地热资源协同互补,提高开发效率。我国目前煤系气井总体单井产量低,且开发技术尚待成熟,这些因素限制了煤系天然气的高效开发。因此,探讨了我国煤系天然气开发的重点攻关方向,包括大力开发深部煤层气资源,增加深部煤层气资源量和储量,突破深部复杂地质条件开采难题;大力实施煤系多类型天然气共探共采,降低煤系多气勘探开采成本并提高煤系气单井产量;大力推动煤矿CH4零排放,降低CH4温室气体排放,提高矿井瓦斯抽采量对天然气产量贡献度;强化CCUS+煤系气资源高效开发,实现CCUS技术与煤系气开发融合发展;强化煤系气开发地质工程一体化,增强煤系气开发技术与储层地质条件的匹配性;促进煤系气开发的数字化和智能化发展进程,利用数字化和智能化技术提升煤系气资源的高效、绿色及低碳开发水平。Natural gas resources are the transition from fossil to non-fossil energy.Coal-measure natural gas is an essentialpart of natural gas.To give full play to the advantages of coal measure natural gas development in China’s dual-carbon strategy,the value and development direction of efficient development of coal-measure natural gas in energy transition are studied.The results show that China’s coalmeasure natural gas resources are diverse,abundant,and widely distributed,providing a solid foundation for large-scale and efficient development.The efficient development of coal-measure natural gas resources is of great significance for promoting low-carbon energy development,which can effectively reduce the proportion of high-carbon fossil energy consumption,help reduce CH4 greenhouse gas emissions,and realize the double effect of increasing production and reducing carbon by combining with CCUS technology.In addition,it plays a significant role in promoting the development of new energy sources,which can guarantee the high-quality peak regulation of new flexible power systems,safer hydrogen production and storage,and synergistic and complementary geothermal resources to improve development efficiency.At present,the overall single-well production of coal-measure gas wells in China is low,and the development technologies remain immature,which constrains the efficient development of coal-associated natural gas.Therefore,this study explores the key directions for advancing coal-measure natural gas development in China,including:vigorously developing deep coalbed methane resources to increase the amount and reserves of deep coalbed methane and overcome the challenges associated with complex deep geological conditions;actively implementing integrated exploration and production of multiple types of coal-measure natural gas to reduce exploration and development costs and enhance single-well productivity;promoting zero CH4 emissions from coal mines to reduce CH4-related greenhouse gas emissions and increase the contribution o
