With geophysical logging applied at Shuanglong well field of Xishui County in the Qianbei coalfield as an example and by utilizing known coal seams or beds of interest and adopting such methods as geological boundary characteristic method, geological marked bed characteristic method, coal seam sequence interpretation characteristic method and coal seam inter-layer distance comparison characteristic method, the authors made a comparative analysis of logging anomaly characteristics revealed along a single curve or multiple curves of physical parameters and summed up common interpretation methods and experience obtained in coal seam judgment and coal seam sedimentary sequence numbering so as to determine coal resource reserves.
