Generally, logging curve shape and logging data are used to identify and evaluate the reservoir and caprock in the study of reservoir-caprock assemblage in conventional logging method, which fails to distinguish the reservoircaprock assemblage and allocation relation of different producing layers (high and low production gas layer, dry layer). In order to analyze and discriminate the types of reservoir-caprock assemblage and the corresponding productivity quickly and accurately, the dual logging parameter method is put forward to study reservoir-caprock assemblage and predict its productivity. Besides, discrimination standard and allocation relationship of reservoir-caprock assemblage determined by the dual parameters of reservoir porosity and caprock porosity are also established.
