基于比德-三塘盆地比德区块煤炭地质勘查及煤层气井取得的地质成果，对煤储层特征及有利区进行了研究。分析认为：该区块煤层厚度总体呈西北薄、东南厚的特点，且主力煤层厚度较大，平均为7.0m；煤的宏观煤岩类型多为半暗煤，其次为半亮煤，显微组分以镜质组为主，平均为67.11%；煤储层孔喉均一性较好，渗透率较高，有利于煤层气的渗流；主力煤层VL平均为26.4 cm3/t，煤岩的吸附能力较强，煤层含气潜力较大。综合分析并根据煤层厚度和埋深初步圈定了煤层气有利勘探区。

Based on coal geological exploration and CBM well acquired geological results in the Bide-Santang Basin, carried out stud?ies on coal reservoir features and favorable exploration area. The analysis considered that the coal thickness in the Bide block presents peculiarity of thin in northwest and thick in southeast, besides, the principal coal seam is rather thick, average 7.0m. The macroli?thotype of coal is mostly semidull coal, then semibright coal;maceral is mainly vitrinite, average 67.11%. Homogeneity of pore throat in coal reservoir is preferable with higher permeability, propitious to CBM seepage. Average VL of principal coal is 26.4 cm3/t;adsorptivity of coal and rock is rather strong, thus larger coal seam gas-bearing potential. On the bases of comprehensive analysis and coal thick?ness, buried depth, preliminarily delineated CBM favorable exploration areas.
