摘　　要：山西省吉县桑峨勘查区位于鄂多斯盆地东缘南段河东煤田乡宁矿区的中部,区内构造简单,煤层分布稳定、厚度大,具有良好的煤层勘探开发前景。在前人研究的基础上,结合桑峨勘探区煤炭勘探成果,从矿区尺度分析了煤层气成藏地质条件。研究认为,本区煤层埋深适中,含气饱和度较低,具有良好的盖层封闭条件,弱径流区和北部含气量较高地区将是本区煤层气勘查的主要目标区。The Sang’e exploration area in Jixian County,Shanxi Province is situated on the Ordos Basin east margin southern sector Xiangning mining area middle part,Hedong coalfield.Structure in the area is simple,coal seams stably distributed with large thickness,thus have good exploitation prospect.Based on previous studies,combined with Sang’e exploration area explored results have analyzed CBM reservoiring geological condition from mining area scale.The study has considered that the area’s coal seam buried depth medium,gas-bearing saturation rather low with good overburden sealing condition,thus the weak runoff area and north part gas content higher area will be the main targets of CBM exploration in the area.
