摘要
中国陆相盆地未成熟石油烃源岩主要形成于受海侵影响的大型湖盆、小型断陷湖盆和膏盐湖盆3种沉积环境。与沉积环境相对应，生油母质依次为藻类、与陆源植物有关的基质镜质体和膏盐环境保存的可溶沥青质及非烃类有机质。细菌改造作用有利于有机质向未成熟石油转化，热作用是未成熟石油形成的重要条件。
The immature source rocks of oil in China's continental basins mainly formed in big lake basins influenced By transgression, small fault-subsided lake and gypsum lake basins. Corresponding source materials were algae, desMonollinite related to terrigenous plant, the soluble asphaltene and non-hydrocarbon organic matter preserved in gypSolyte environment. Bacterial action was favourable for organic matter to be inverted into immature oil, and thermal effect was an important condition for the formation of immature oil.
