摘要
煤层气富集单元划分是探索煤层气成藏规律、进行煤层气资源和选区评价、制定科学的煤层气勘探 程序、提高煤层气勘探成功率的基础。中国煤层气的形成条件与分布环境十分复杂,因此富集单元研究对中国煤 层气的勘探评价尤为重要。据煤层气的特殊性和复杂性,结合我国煤层气的分布情况,建立了我国煤层气富集单 元划分系列,将煤层气富集单元划分为含气区、含气盆地、富气区、富气带和煤层气藏(田)五级。
The division of coalbed methane-enriched units is the basis of probing coalbed methane reservoir formation law, carrying out coalbed methane resource and area-selection evaluation, making up scientific coalbed methane exploration program and raising coalbed methane exploration success ratio. The formation conditions and distribution environments of coalbed methane in China are very complicated, so that it is very important for the coalbed methane exploration evaluation to investigate its enrichment units. According to the particularity, complexity and distribution law of coalbed methane in China, its enrichment units were divided into five grades, i.e. methane-bearing province, methane-bearing basin, methane-rich region, methane-rich zone and methane reservoir (field).
