| 摘 要： | 通过对沁水盆地中-南部井下煤层宏观裂隙的观测和统计, 将其按大小和形态特征划分为四级, 并在扫描电镜下对显微裂隙进行了系统描述和测量。在分析渗透率与地应力 (埋深) 、裂隙、储层压力和水文地质条件等相互关系的基础上, 指出影响本区煤储层渗透率的主控因素是地应力 (埋深), 在埋深相似的条件下, 其他因素对参透率起着更重要的作用。

| Abstract: | Macrofractrues were classified into four ranks,according to measurement and statistics of underground coal mine in central and southern Xinshui basin,and the description and measurement of microfractures under scan electron microscope.Based on the analyses of relationships among permeability and ground stress/buried depth,fractures,reservoir press,hydrogeological condition,it is pointed out that the ground stress/buried depth is the principal control factor.When the buried depth is similar,the other factors play more important role on permeability. |

| Keywords: | coal reservoir ground stress permeability fracture |
