摘　　要：【目的】我国深层煤层气(埋深>1 500 m)资源潜力巨大,作为战略性清洁能源,其开发利用价值日渐凸显,对于促进我国能源结构转型、支撑“双碳”目标具有重大现实意义。近年来在鄂尔多斯、四川、准噶尔等盆地取得重大勘探突破,单井日产气量突破10万m3,初步实现规模化开发。然而,现有煤层气标准体系主要针对浅层资源(埋深<1 000 m),难以适应深层储层高温、高压、高应力、强非均质性、高游离气占比等复杂及特殊地质条件,导致勘探开发技术适配性不足、安全环保风险突出。【方法】通过系统分析深层煤层气地质-工程特征差异,提出“三个维度–四项原则”的标准体系架构,并指出了标准体系建设的阶段目标:短期聚焦勘探精度提升与开发工艺优化,建立地质–工程一体化标准框架,推动技术创新和产业转型升级;中期构建全产业链技术标准集群,推动全生命周期风险管理,实现资源高效利用和投资收益最大化;长期参与国际标准制定,促进国际技术交流和合作,提升我国深层煤层气产业的国际竞争力。【结果和结论】结果表明,深层煤层气标准体系建设应涵盖基础通用、地质勘探、地震测井、开发评价、工程建设和安全环保六大领域,采用“继承性改良+颠覆性创新”相结合的研制策略,重点关注储层评价、甜点评价、压裂改造等核心技术标准的建设。建议通过“标准体系框架构建、关键标准制修订、技术创新与标准化结合、国际合作与交流以及政策支持与保障”等战略路径,加速形成标准化工作格局,为深层煤层气产业高质量发展提供制度保障和技术支撑。[Objective] Deep coalbed methane(CBM;burial depths:> 1500 m) in China holds considerable resource potential.As a strategic clean energy,deep CBM is exhibiting increasingly high value of exploitation and utilization.This is of great practical significance for China's energy structure transformation and the achievement of peak carbon dioxide emissions and carbon neutrality in the country.In recent years,breakthroughs have been made in deep CBM exploration in basins such as Ordos,Sichuan,and Junggar,with a single-well daily gas production exceeding 100 000 m3,marking the initial achievement of large-scale deep CBM exploitation.However,the existing standard system,primarily designed for shallow CBM resources(burial depths:< 1 000 m),is difficult to adapt to the complex,unique geological conditions of deep CBM such as high temperature,high pressure,high stress,strong heterogeneity,and high free gas content.This leads to insufficient technical adaptability and pronounced risks of safety and environmental protection in the exploration and exploitation of deep CBM.[Methods] Through a systematic analysis of differences in geological and engineering characteristics between shallow and deep CBM,this study proposed a standard system framework following three dimensions(i.e.,geological complexity,technical adaptability,and industrial and ecological collaboration) and four principles(scientific,systematic,practical,and dynamic natures).Furthermore,this study determined the staged objectives for the standard system construction.Specifically,the short-term objective is to establish a geological and engineering integrated standard framework by focusing on the improvement in exploration accuracy and the optimization of exploitation processes,aiming to drive technological innovations and industrial transformation and upgrading.The medium-term objective is to establish a technical standard cluster covering the entire industry chain while promoting the whole life cycle risk management,with the purpose of achieving efficient resource
