Distributional signatures of depositional system of Pinghu Formation, Pinghu slope, Xihu Sag, East China Sea Shelf Basin

  • 摘要: 东海陆架盆地西湖凹陷平湖斜坡带始新统平湖组是目前已证实的主力油气富集层系,对其沉积体系已开展过多轮研究,但是仍然存在很大争议。在前人研究的基础上,基于新处理的三维地震、岩心和多种地球化学测试等资料,对平湖斜坡带平湖组沉积环境和沉积体系重新展开了系统分析。平湖斜坡带主要发育三种沉积体系类型:河控三角洲、潮汐改造为主的三角洲和潮坪沉积体系。这三种沉积类型在平面上具有明显的分区性,平北地区以河控三角洲沉积为主,平中地区发育受潮汐改造的三角洲沉积,平南地区处于半封闭海湾湾口,以潮坪体系为主,洋流控制着砂体的空间展布形态和规模。整体而言,平湖斜坡带平湖组沉积格局从北向南表现出受海水影响逐渐加强的变化规律。
