摘　　要：通过梳理中国页岩气地质理论研究进展与勘探实践,分析和总结不同类型页岩气地质特征、富集规律与资源潜力,取得以下认识:①中国的海相、海陆过渡相、陆相页岩在地质年代上由老到新分布,构造改造和生烃演化过程复杂度逐渐降低。②沉积环境控制源储配置类型,是“成烃控储”的基础,海相和陆相源储配置类型以源储一体型为主,偶见源储分离型,海陆过渡相以源储一体型和源储共生型为主。③刚性矿物抗压保孔和地层超压控制源储一体型页岩气的富集,良好的源储耦合与保存条件控制源储共生型和源储分离型页岩气的富集。④海相依然是中国页岩气增储上产主阵地,过渡相和陆相有望成为重要接替领域。建议按照3个层次开展页岩气勘探部署,加速展开中上扬子地区海相志留系、寒武系和二叠系勘探;重点突破中上扬子地区海相超深层和华北地区奥陶系等海相新层系、石炭系—二叠系海陆过渡相以及四川、鄂尔多斯、松辽等盆地中生界陆相页岩气领域;探索准备华南和西北等新区页岩气领域,为中国页岩气持续发展提供技术与资源储备。By reviewing the research progress and exploration practices of shale gas geology in China,analyzing and summarizing the geological characteristics,enrichment laws,and resource potential of different types of shale gas,the following understandings have been obtained:(1)Marine,transitional,and lacustrine shales in China are distributed from old to new in geological age,and the complexity of tectonic reworking and hydrocarbon generation evolution processes gradually decreases.(2)The sedimentary environment controls the type of source-reservoir configuration,which is the basis of"hydrocarbon generation and reservoir formation".The types of source-reservoir configuration in marine and lacustrine shales are mainly source-reservoir integration,with occasional source-reservoir separation.The configuration types of transitional shale are mainly source-reservoir integration and source-reservoir symbiosis.(3)The resistance of rigid minerals to compression for pore preservation and the overpressure facilitate the enrichment of source-reservoir integrated shale gas.Good source reservoir coupling and preservation conditions are crucial for the shale gas enrichment of source-reservoir symbiosis and source-reservoir separation types.(4)Marine shale remains the main battlefield for increasing shale gas reserves and production in China,while transitional and lacustrine shales are expected to become important replacement areas.It is recommended to carry out the shale gas exploration at three levels:Accelerate the exploration of Silurian,Cambrian,and Permian marine shales in the Upper-Middle Yangtze region;make key exploration breakthroughs in ultra-deep marine shales of the Upper-Middle Yangtze region,the new Ordovician marine shale strata in the North China region,the transitional shales of the Carboniferous and Permian,as well as the Mesozoic lacustrine shale gas in basins such as Sichuan,Ordos and Songliao;explore and prepare for new shale gas exploration areas such as South China and Northwest China,providing technology and re
