从构造、含煤地层特征、含气量和储层物性特征四个方面探讨了鹤岗盆地煤层气资源潜力。结果表明：鹤岗盆地煤层厚度大、埋藏适中、含气量较高都显示出较好的生气能力;断裂十分发育导致煤岩结构破碎、渗透率差,是破坏煤层气发规模富集的不利因素;鹤岗盆地资源量丰富,及时调整勘探思路,寻找小规模富集区,面积降压,是将资源量转化为储量的突破方向。

The paper discusses the potentials of CBM resources in Hegang basin from four aspects： namely, tectonics, characteristics of coal - bearing strata, gas contents, and the physical characteristics of reservoir. The results show the following facts： 1 ） The vitality of the basin is great： for example, great thickness of coal seams in Hegang basin, moderate burial occurrence, and high gas contents; 2） The fractures are well devel- oped, which lead to fractured structures and low permeability of strata, which are unfavorable factors influenc- ing large scale enrichment of CBM; 3） CBM resources are abundant in Hegang basin. The exploration concept should be adjusted in time and try to find out small scale enrichment region. The direction of breakthrough is to carry out area pressure relief in order to convert the resources into reserves.
