盐湖盆地沉积与油气形成的关系

我国广泛发育着盐湖盆地，这些盐湖盆地具有独特的沉积环境和生油气条件。盐湖相烃源岩及其所形成烃类的地球化学特征，既不同于淡水湖相，又不同于海相烃源岩及原油的地球化学特征。盐湖盆地的石油资源勘探，长期以来一直是国内外石油界所关注的一个研究领域。勘探实践表明，世界上大多数盐湖盆地都是含油气区。从盐湖沉积的形成等几个方面来讨论其与油气形成的关系。

The Relation Between Salinelakes Basin Sediment and Petroleum Generation

Saline lakes are extensively developed in China.There are unique sedimentary environment and condition of hydrocarbon generation in these saline lakes.The geochemical characteristics of source rocks and hydrocarbons generated from saline lakes sedimentary environment are different to those generated from fresh water lacustrine facies and those generated from marine facies.Exploration of oil resource of salinelake basin was always research region that was taken much attention by domestic and oversea oil industry. The practice of exploration indicated that the most of salinelake basin in the world all are oilness region.This paper discussed the relation between salinelake basin sediment and petroleum generation through researching the coming into being of salinelake sediment.
