摘　　要：陆相断陷盆地不同级别的层序地层是不同层次构造运动形式的物质体现,也以不同的方式对应着不同类型的石油地质要素。盆地不同级别成藏单元成因划分的基础是不同层次的成藏要素类型及其作用,通过不同级别层序地层、地质要素及其作用内在联系的分析,认为不同级别的层序地层单元与成藏单元之间可以建立起成因类比关系,一级层序、二级层序、三级层序分别以不同的方式对应于含油气盆地、含油气系统或复式油气聚集带、成藏组合体,从而更加深入地反映陆相断陷盆地等时成因地层格架与成藏单元结构间的内在成因联系。Sequence stratigraphy units at various levels are the results of tectonic movements at various levels and all correspond to petroleum geologic elements with different types at different ways in the continental downfaulted basin. The foundation of origin classification of reservoir - forming units at different levels in the basin is the types and the function of reservoir- forming elements at various levels. The intrinsic relationship of the sequence stratigraphy, geologic elements at different levels and their function are analyzed. It indicates that sequence stratigraphy units at various levels have the internal genetic relations with reservoir -forming units at various levels in the continental downfaulted basin. First - order sequence, second - order sequence and third -order sequence separately correspond to petroliferous basin, petroliferous system or multiple - oil - gas accumulation belt and reservoir - forming assemblages with distinct manner. The internal genetic structure relationship between the stratigraphic framework and the reservoir - forming units with isochronal genesis in the continental downfaulted basin may be reflected more deeply.
