摘要(Abstract)：

渤海湾盆地渤中凹陷25-1油田沙三段主要发育低渗—特低渗型岩性油气藏,沙三段沉积相特征及其分布认识程度低。利用岩心观察、薄片鉴定和粒度统计,结合钻测井资料,研究渤中凹陷25-1油田沙三段沉积物类型、沉积特征、沉积序列及沉积相展布。结果表明:渤中凹陷25-1油田沙三段近岸水下扇主要发育具有鲍马序列的浊积岩、砂质碎屑岩和滑塌岩三种重力流沉积物,其中浊积岩分布于中扇辫状水道间、中扇前缘及外扇,砂质碎屑岩是内扇—中扇水道的主体组成部分,滑塌岩发育于全区同沉积断层活动带;扇体沙三段自下而上依次发育内扇—中扇—外扇的退积型沉积序列;自沙三段初期发育近岸水下扇且扇体规模最大,随之湖平面逐渐上升、构造活动减弱导致扇体向西南侧迁移并开始萎缩,沙三段末期扇体面积仅为原始面积的二分之一。该结果为渤中凹陷25-1油田未来勘探开发提供指导。
