| 摘 要： | 水文地质条件作为煤层气保存及形成超压煤储层主要因素之一。它对煤层气赋存、运移和生产都会产生影响与控制作用，对煤层气的高产富集和开采也起到非常重要的作用，是煤层气富集成藏过程主控因素中的一个关键因素。结合沁水盆地、鄂尔多斯盆地等一些国内煤层气区块，研究水文地质对煤层气富集的影响。

| Abstract: | The factors which influence the enrichment of coalbed methane （CBM） mainly involves air condition, CBM reservoir capacity, the physical properties of coal, the hydrogeological conditions and reserving process and so on. Hydrogeological condition, as one of the main factors influencing the preservation and formation of CBM overpressure coal mine, can affect and control the accumulation, migration and production of CBM and determine the enrichment and development of CBM. Hydrogeological condition is regarded as a key factor to research CBM reserving process. Based on Qinshui Basin, Ordos Basin and some other domestic CBM blocks, the paper mainly describes the influence of hydrogeological conditions.on the enrichment of coalbed methane. |
