     The coal beds in Hegang Lease are characterized by big thickness, moderate buried depth and much higher gas resources, and moreover show pretty favorite gas productivity, but can not reach the industrial standards. On the bases of the following existed data such as wells, experimental analyses, seismic informations and so on, five key reservoir-accumulating and gas controlling factors are comprehensively analyzed： seam thickness, buried depth, evolution degree, permeability, gas-bearing and preserving conditions. The studies prove that partial coal seams in Xinyi Block have undergone magmatic action, the coal rank is enhanced higher, so the CBM productivity becomes much better; the coal beds in Nanyi and Xinyi Blocks are pretty thick and wide-distributed, the buried depth is moderate, the preserving conditions are much better, so they are the next preferential exploration areas; the developed degree of the faults and the sealing condition of top and bottom plates are the key factors of controlling the size of CBM reservoir accumulation.
