摘要(Abstract)：

全球碳排放量增加，气候变暖严重，碳封存逐渐引起重视。CO_2地质封存是一种非常有效的减碳方式，其中页岩是一种具有广阔前景的碳封存地质体。中国拥有多个大型的页岩油气盆地和普遍发育的页岩储层，具有巨大的CO_2地质封存潜力，同时可以提高油气采收率。基于前人关于页岩CO_2地质封存的研究，梳理和确定了页岩储层中CO_2以吸附封存为主，进一步总结了页岩储层碳封存受温度和压力、有机质含量、孔隙结构等因素的影响。同时，基于我国主要页岩油气区储层条件，进行了初步的碳封存潜力评价，结果表明页岩中的CO_2封存总量约为463Gt，相当于中国40多年的碳排放量，页岩储层CO_2地质封存潜力巨大，值得关注。

关键词(KeyWords)： 页岩储层;二氧化碳地质封存;封存机理;影响因素;潜力评估
