摘　　要：针对低温氮吸附实验法对孔隙结构类型解释混乱问题,论述了低温氮吸附实验在页岩储层微观孔隙表征中的机理,并对典型的低温氮吸脱附曲线进行详细解剖,最后建立了一套低温氮吸附法表征储层微观孔隙结构的评价标准体系,且应用实例论证了其可行性。At present,the experiment methods of low temperature nitrogen adsorption in shale reservoir pore structure have been widely used. But the interpretation of the adsorption stripping curve about the type of shale reservoir microscopic pore structure is chaos. Based on this,the mechanism and characterization of low- temperature nitrogen adsorption experiments in shale microscopic pore reservoir was emphatically discussed,and the typical cryogenic nitrogen stripping absorption curve was explained in detail. Then,the evaluation standard system of low- temperature nitrogen adsorption in shale reservoir microscopic pore structure was developed. Engineering practice demonstrated its feasibility,and the study gives reference to the evaluation of shale and coal reservoir pore structure.
