| 摘 要： | 根据区块煤田地质及煤层气地质勘查资料，对贵州保田一青山区块煤储层特征及煤层气含量进行研究。区内主要为中灰、相对富氢、低挥发分无烟煤。煤层气含量受埋深、构造、显微煤岩组分等因素影响。区块内地质构造较简单，含煤面积大（1009km^2），煤层气资源丰度高，含气量较高，煤储层厚度大，可采性好，具备良好的煤层气开发地质条件，煤层气总资源量估算结果为2166．74×10^4m^3。老厂、地瓜坡勘查区煤层气资源量多，地质、交通等条件好，是煤层气开发的首选区。

| Abstract: | Based on geological and CBM exploration data carried out studies on coal seam reservoir characteristics and CBM content in the region. Coal in the region is mainly medium ash, relatively hydrogen rich and low volatile matter anthracite. CBM content is influenced by coal depths, structures and macerals. The region is geological structure simple, large coal-beating area （1009km^2）, high CBM resource abundance and content, thick coal seam reservoir, good workability, has better CBM exploitation geological conditions, estimated total resources 2166.74×10^8m^3. In Laochang and Diguapo exploration areas have abundant CBM resources, better geological and traffic conditions thus the preferred CBM exploitation region. |
