摘要

摘要: 湖盆充填样式是评价烃源岩沉积学特征的重要手段。文中通过分析东营凹陷下第三系沙河街组烃源岩的沉积序列、地层发育特征和盆地充填演化过程,结合烃源岩的地球化学特征,将沙河街组烃源岩自下而上划分为3个发展演化阶段,并建立了蒸发岩相组合模式(沙四上亚段)、波动深湖相组合模式(沙三下亚段)和三角洲-湖泊相组合模式(沙三中亚段和沙三上亚段),它们分别对应了欠充填、平衡充填和过充填的湖泊类型,反映了湖泊从开始形成、扩张壮大到萎缩消亡的过程。

Abstract: The infilling patterns of lacustrine basins are the important means to evaluate the sedimentary characteristics of hydrocarbon source rocks.Combined with the geochemical characteristics of source rocks in this paper,the sedimentary succession of source rocks,the developing features of strata and the infilling and evolutionary process of basins in the Lower Triassic Shahejie Formation of the Dongying Depression were analysed.The source rocks of the Shahejie Formation can be divided into three evolutionary stages from lower to upper.The evaporite facies(the Upper Shasi Subformation),the oscillatory deep lake facies(the Lower Shasan Subformation)and the delta lacustrine facies(the Middle and Upper Shasan Subformation)assemblage patterns were established,which corresponding to underinfilling,equilibrium infilling and overinfilling lacustrine types respectively.They reflected the generation,spreading and consumption process of lakes.
