| 摘 要： | 淮南地区构造位置处于华北地台东南部，是一呈北西西向展布的复式向斜。区内二叠系煤层厚度大，分布面积广，资源丰度为1．334×108m3／km2,具有较高的资源潜力。但由于煤的变质程度较低，煤质较差，加上逆掩断裂的挤压作用，使地层有效地应力较高、造成煤储层渗透性较差；再者，煤储层的含气饱和度较低，开煤层气的产出较为不利；但在构造的转折端及背科的倾伏部位，存在着微裂隙较发育的地应力低带，有希望找到煤层气勘探开发的有利区。

| Abstract: | The coal bearing strata in Huainan area is situated in the south-east portion of the North China platform,a synclinorium with northwest by west.In the Permian of the area,the coal resources is 1.33 × 108m3/km2, but it is disadvantageous to produce the coalbed gas for low permeability of coal reservoir. In turning point and anticlinal p1unging portion -microfracture development and low stress area,it is favorable to prospect a coalbed gas. |
