| 摘 要： | 从天然气成因机理和成藏机理两个方面对天然气类型进行划分,天然气成因机理分为有机成因气和无机成因气;天然气成藏机理分为煤层气、页岩气、水溶气、根缘气(深盆气)、常规气以及气体水合物等。在天然气分类基础上,认为天然气在运聚过程中存在天然气成因机理和成藏机理两种序列关系,不同的天然气机理类型之间存在着过渡关系,两种机理分类不是孤立的而是相互联系的,具体运用到前陆盆地与裂谷盆地中,提出了前陆盆地与裂谷盆地的气藏可能分布模式。

| Abstract: | Natural gas can be classified by gas formation mechanism and accumulation mechanism.According to gas formation mechanism,the types of gas can be divided into organic genetic ones and inorganic genetic ones.From gas accumulation mechanism,the types of gas can be divided into the coal-bed gas,shale gas,source-contacting gas or basin-centered gas and tight-sand gas,dissolved gas,normally trapped gas and hydrate etc.Based on the gas classification,it is thought that gas formation spectrum and accumulation spectrum exist in the process of gas migration and accumulation.There are transitional relations among different gas types.The two sorts of mechanisms are not independent but interrelated.Furthermore,the distribution modes of gas accumulation in foreland basins and rift basins are presented. |
