摘要
水文地质条件对煤层气赋存、运移影响很大 ,对煤层气的开采至关重要 .从分析实际资料出发 ,论述水文地质条件对煤层气赋存的控制作用 ,提出了水文地质控气特征的 3种作用形式 :水力运移逸散作用 ;水力封闭作用 ;水力封堵作用 .其中 ,前一种作用导致煤层气散失 ,后两种则有利于煤层气保存 .
Based on analysis of actual geologic and hydrogeological information, controlled characteristics of hydrogeological conditions on the coalbed methane migration and accumulation is discussed. The three patterns of hydrogeological characteristics of coalbed methane controlled is suggested, i.e., the hydraulic migration escape, the hydraulic sealed and the hydraulic jam up. The pattern of the hydraulic migration escape leads to the coalbed methane escape and is unfavorable of the coalbed methane accumulation. Conversely, the hydraulic sealed and the hydraulic jam up process are favorable of the coalbed methane accumulation.
