摘要
为了探讨文留地区盐岩的形成机理 ,分析盐岩与油气的聚集关系 ,归纳总结了文留地区下第三系沙河街组盐岩分布特征 ,利用古生物种群演化和构造发育史理论 ,对文留地区盐岩进行深入细致的研究 ,结果给出了本区成盐模式的合理解释及其与油气聚集的关系。认为文留地区沙三段盐岩为陆相湖盆深水—半深水成盐模式 ,沙一段盐岩具有干盐湖沉积模式 ;盐岩与油气关系密切 ,在盐间和岩性相变带寻找隐蔽性油气藏具有广阔的前景。
This paper is focus of the theory of paleogene salt rock sedimentation in the Wenliu region,analyses the relation between the salt rock and oil-gas gathering.According to the deeply study of salt rock characteristics,paleospecies evolution,structural history,it gives the reasonable explain of salt sedimentation model,at the same time,also points that the third member of Shehejie salt rock are formed in the environment of continental lake-basin abyssal or bathyal sediment,the first member of Shehejie is formed in the environment of dry lake-basin sediment.finally the author concluded that there are promising prospects for explosion in the salt inter-stratum and salt rock translation belt of Wenliu region.
