摘    要:页岩气是以吸附或游离状态为主要存在方式的天然气聚集,其吸附及解吸机理与煤层气类似.根据不同的成藏条件,可表现为典型的吸附机理、活塞运聚机理或置换运聚机理.页岩气的分布主要受页岩厚度、面积、有机质丰度、生气强度及页岩储集空间等因素控制.中国对页岩气的研究起步较晓,但经国内外页岩气藏的初步对比分析后发现,中国许多盆地与美国...

关 键 词:页岩气  成藏条件  分布规律  研究现状  发展趋势

Abstract:Shale gas is a kind of natural gas gathering in free and absorbent forms.At the same time,its resolution mechanism is analogous to coalbed methane(CBM).Due to the different storage characteristics,shale gas can show absorbent mechanism,the piston principle of migration and accumulation mechanism,and the displacement principle of migration and accumulation mechanism.The distribution of shale gas is affected by many elements,such as the thickness and area of shale,the abundance of organic in shale,the strength of gas production,and the crack or pore in shale reservoir.The study of shale gas is late in China.But after comparing reservoir-forming conditions at home and abroad,it is found that there are many basins in China which are analogous to that in the eastern U.S.in geologic conditions for shale gas formation,especially the Lower Cambrian Qiongzhusi Formation and the Lower Silurian Longmaxi Formation in South China have favourable reservoir-forming conditions.There are many issues and questions in front of China in studying shale gas.So,the study of the basic theories about shale gas,especially the geologic conditions,the accumulation mechanism,the distribution regularities,the appraisal system,the development technique and so on,will be the main trend in the future comparative long time.
Keywords:shale gas  accumulation condition  distribution regularity  study situation  development trend
