页岩气渗流机理研究中,纳米孔隙中的渗流和多尺度储渗空间中气体传质的研究条件还都不成熟,唯吸附与解吸附的研究仅通过宏观实验就可进行.目前国内页岩气的研究热点也主要在与工艺密切相关的领域,对页岩气渗流的起点或基础——吸附和解吸附关注相对较少.对页岩气对吸附与解吸附机理国内外研究现状就行分析,并提出一系列值得深入研究的问题或方向.页岩气的主体赋存状态存有争议,对固溶态的甲烷的研究还很少；页岩气含气量测试中解吸法和等温吸附实验及其数学解释模型可靠程度有待提高；甲烷在超临界状态下的吸附规律研究较少,相关吸附模型对此鲜有涉及；单一矿物和有机质的吸附特性关注较少,多组分气体中各气体间竞吸机理还未有详细研究.%In the research of flow mechanism,flow of gas in nanoscale pores and mass transfer process of multimechanism of gas in multi-scale porous media are difficult to study on the condition at present,only the gas adsorption and desorption which is starting and basis of mass transfer of gas in the shale can research by adsorption isotherm and desorption experiment,but it attracted less attention while process are research focus generally.So the research status of mechanism of adsorption and desorption at home and abroad is analyzed,and a series of research questions and directions are presented.There are many different opinions about main occurrence of shale gas,and research to solid solution of methane is insufficient; the reliability of adsorption isotherm and desorption experiment and they explanatory model needs improving; the adsorbing law of supercritical methane is unknown; The adsorption of multicomponent gas to shale and its mineral and organic matter composition aren' t study meticulously.
