摘 要: 从页岩气的赋存形式、孔隙结构、黏土矿物、有机碳总含量(total organic carbon,TOC)和镜质组反射率(reflectance of vitrinite,Ro)等多个角度,探讨了页岩气储层对CO2的吸附、解吸性能研究现状,并分析了关键问题和研究热点、难点。分析表明:国内外对于CO2与CH4在煤层中的吸附、解吸性能研究颇为深入,由于煤层与页岩气储层的相似性,该研究对CO2驱替页岩气并储存的研究奠定了坚实基础。系统研究页岩对CO2的吸附、解吸机理,以及注入CO2前后页岩孔隙结构的演化将是今后的一个重点研究方向。
关 键 词: 地质学;页岩气;综述;CO2地质储存;孔隙结构

Abstract: Through consulting massive literatures, the present situation of the properties of CO2 adsorption and desorption in shale gas reservoir was discussed from the reserve form of shale gas, pore structure, clay mineral, content of total organic carbon (TOC) to the reflectance of vitrinite (Ro). The key problems, research hotspots and difficulties were analyzed. The analysis show that the research of the performance of the adsorption and desorption of CO2 and CH4 in coal seam is thorough both from home and abroad. Due to the similarity between coal and shale gas reservoirs, the research laid a solid foundation on CO2 flooding shale gas and storing. Systematic studies for the adsorption and desorption mechanism of CO2 in the shale as well as the evolution of shale pore structure before and after the injection of CO2 will be a key research direction in the future.
