摘　　要：煤储集层是一种特殊的储集层 ,其孔隙特征、渗流能力、吸附能力等主要受煤的原始组分、变质程度两大因素控制 ,煤层作为储集层时所表现出的特殊性 ,与常规砂岩储集层在生储气方式、生储气能力、开采范围和方式、储层孔渗性等方面存在许多不同之处 ,全面了解和认识二者的特性 。The coal reservoir is a special reservoir, its pore features, percolation flow capacity, adsorption capacity are mainly controlled by two coal factors, original composition and metamorphic grade. As a type of reservoir, coal bed indicates its particularity and has much difference in gas generation and storage mode, gas generation and storage capacity, recovery scope and mode, reservoir pore permeability and other aspects compared with conventional sandstone reservoir. To overall understand and know the features of the two has certain guidance for properly evaluating coal gas reservoir. Subject heading
