RESERVOIR-FORMING PATTERN OF THE SOUTH UPLIFT IN ENPING SAG

  • 摘要: 南部隆起带是恩平凹陷的主要成藏带。利用基础资料, 系统分析了南部隆起带油气成藏的条件与特征, 总结了南部隆起带油气成藏的模式。恩平凹陷南部隆起带油气主要来自北侧EP17洼始新统文昌组中深湖相烃源岩, 南部隆起带之下缺失文昌组沉积, 存在油气的有利仓储区, 油气通过沟通有利仓储区的断裂运移, 主要有仓上-上盘诱导裂缝带垂向输导-连通砂体侧向输导-滑动破碎带侧向封堵-断块油气藏、仓上-上盘诱导裂缝带垂向输导-连通砂体侧向输导-它源自圈背斜油气藏以及仓上-下盘诱导裂缝带垂向输导-连通砂体侧向输导-滑动破碎带侧向封堵-断鼻油气藏3种成藏模式。
