摘　　要：页岩气藏属于含有大量吸附态天然气的致密性气藏,相比常规气藏有其独特之处,为了更有效地开发页岩气藏,在综述国内外大量研究成果基础上,介绍并分析了页岩气藏的储集特征、孔渗特征及吸附-解吸规律解,页岩气微观运移方式、流态判断以及对产能的影响;指出页岩气与煤层气的解吸、微观运移特征有很大差异,因此,今后建立适合页岩气解吸的吸附模型、分析页岩气的微观运移机理、特征及影响产能的主控因素等问题值得进一步研究。Shale gas reservoir belongs to tight gas reservoir, with a large number of adsorbed natural gas. Compared to conventional gas, shale gas reservoir has its unique features. In order to develop shale gas reservoir more effectively, this paper introduces and analyzes the characteristics of shale gas reservoir, po-rosity and permeability characteristics and adsorption desorption rules solution, shale gas micro-migration patterns, flow pattern judgment and influence on productivity, on the basis of large number of domestic re-search. This paper points out that shale gas and coal-bed methane desorption, microcosmic transport char-acteristics are different. Therefore, the establishment of suitable shale gas desorption-adsorption model, shale gas development on microcosmic transport mechanism characteristics and main controlling factors of influencing shale gas productivity should be made further research.
