     Based on the deep analysis and research on the difficulties of identifying water-soluble methane gas reservoir in Tertiary Zhangjiapo Formation sandstone reservoir in Weihe Basin, combined gas logging data, the article was written to solve the difficulties of identification and interpretation about gas- and water-bearing layers, and to provide better services for exploitation of water-soluble gas unconventional new energy exploration. The authors established a set of standards such as porosity overlapping contrast method, porosity difference and ratio （ porosity parameter method）, and contrastive analysis between compensation neutron and compensated density curves which are suitable in the study area and the TNIS imaging logging to recognize integratedly gas- and water-bearing layers. The standards have been used in the twenty-eight sections in the study area. And compared with the practical production, the compliance rate was 90% , indicating application effect of this method was good. The method may provide reference and guidance for exploration and development of other water-soluble gas basin.
