摘　　要：煤层气的赋存和聚集受到水文地质条件的影响。从水文地质分析的角度出发,对榆社—武乡区块煤层气赋存状况进行了评价,通过分析区块地下水动力条件、地下水水头压力,建立了本区煤层气富集模型,对煤层气开发甜点区进行预测,利用目前开发的煤层气井进行了验证。结果表明,目前已施工排采井的排采情况与预测的2处甜点区基本吻合。CBM hosting and accumulation will be impacted by hydrogeological conditions.Start from hydrogeological condition analysis point of view has assessed CBM hosting status in the Yushe-Wuxiang block.Through analyses of groundwater hydrodynamic condition and head pressure in the block have established the area’s CBM enrichment model;carried out prediction of CBM exploitation dessert areas;through current exploitation CBM wells carried out verification.The result has shown that CBM drainage status of present constructed drainage wells are basically tally with the predicted two dessert areas.
