摘要
我国众多含油气盆地同样具备页岩气形成的基本地质条件。本文通过分析我国含油气盆地页岩分布,依据中国页岩气发育区的地质特征,利用类比法初步估算中国主要盆地和地区的页岩气资源量约为21.5×1012~45×1012m3,中值为30.7×1012m3。主要分布在南方聚气区、华北聚气区,古生界页岩气资源量大约是中生界页岩气资源量的2倍,四川盆地东部和南部下寒武统和下志留统页岩是目前勘探的主要层系。
Most of China's oil bearing basins have had primary conditions for occurrence of shale gas. Based on the studying on the distribution and geological features of shale in China's major oil-bearing basins,the resources of shale gas in China's major basins and areas has been evaluated using analog method. The result shows the total of resources amounts to (21.5~45)×10^12 m^3,with a mean value of 30.7×101^2 m^3. The shale gas resources are distributed mainly in southern China and North China. Among them,the resources of Paleozoic shale gas takes account for as twice much as that in Mesozoic shale gas. Therefore,the Lower Cambrian and Lower Silurian shales in the eastern and southern parts of the Sichuan Basin is the major sequence to prospect.
