| 摘 要： | 通过对阳信洼陷构造和地层特征的研究,从油气源、储层特征与储盖组合、油气藏类型等方面分析了油气成藏特征。油气成藏与分布主要受油气源、油气运移方向、构造和岩性等因素控制,沙四段上亚段充足的油气源是油气富集的重要条件,油气运移以层内侧向运移方式为主,位于油气运移指向的圈闭有利于成藏,大型的背斜构造和断裂鼻状构造背景是油气聚集的主要场所,构造和岩性因素控制了油气的分布。

| Abstract: | Based on study of the structural and stratigraphic features of Yangxin depression, oil/gas reservoiring characteristics are analyzed in respects hydrocarbon sources, reservoir characteristics, combination of cap rock and reservoir rock, as well as reservoir types. Oil/gas reservoiring and distribution are mainly controlled by hydrocarbon sources, direction of hydrocarbon migration, structure and lithology. The abundant hydrocarbon source in the upper 4th member of Shahejie Fm is an important factor controlling oil/gas enrichment. Hydrocarbon migration is characterized by intraformational lateral migration. Traps located in the direction of hydrocarbon migration are favorable for reservoiring. Large anticlinal and faulted-nose structures are the main sites for oil-gas accumulation, and oil-gas distribution are controlled by structure and lithology. |
