中国大陆区煤层气盆地划分原则与方案探讨

Divisional Principles and Projects of Coalbed Methane Basin in China's Mainland

从煤层气富集成藏地质条件分析入手,在研究聚煤盆地的时空演化、后期改造特征基础上,将煤层气盆地定义确定为"具有工业价值煤层气藏形成和保存条件的含煤盆地",煤层气盆地群是指具有两个以上的小含煤层气盆地的地区。在充分参考盆地、含油气盆地、聚煤盆地划分方案基础上,提出一种以现今含煤盆地进行划分的煤层气盆地划分方案,并提出地质与物探资料综合确定煤层气盆地边界的原则,将我国大陆区煤层气区划分为64个煤层气盆地。

On the analyses of geological feature of coalbed methane accumulation, this paper confirms the definition of coalbed methane basin is bearing industry value coalbed methane basin, with study on the spatial-temporal revolution of coal accumulation basin. Based on the division project of oil and gas-bearing basin, it gives the principles of delimitation and division of coalbed methane basin, on the basis of bearingcoal basin. In China's Mainland, it can be divided into 64 basins.
