以霸县凹陷古近系地层为例, 分析凹陷的内部结构和层序地层构型。牛东断层及其导致的凹陷结构的“东西分带”与斜坡形态的“南北分段”将霸县凹陷分为3 个构造- 地貌单元, 即南、北、中3 段。各段的层序地层构型、物源体系发育程度、沉积体系与砂体成因类型、砂体与构造- 地貌配置样式具有明显的差异性。

The inner architecture and sequence configuration of the Paleogene in Baxian Sag are analyzed. Niudong fault and the related E-W zonation and S-N segmentation divide Baxian Sag into three structure-geomorphic units ( the south, north and middle segment) . The sequence configuration, development degree of provenance system, the depositional system and the genetic type of sand bodies, and the allocation type between the sand bodies and the structure-geomorphy of each segment are apparently different.
