黄珏油田戴南组高分辨率层序地层特征研究

摘要

根据黄珏油田戴南组地震波组特征及内部反射结构,识别出戴南组内部在层序划分中为重要边界识别标志的两个上超面,即低角度上超面和高角度上超面;以边界断层活动差异、物源供给转换及A/S比值的变化为依据,将戴南组地层划分为3个长期旋回,10个中期旋回,确定了地层旋回叠加样式。结合储层特点建立了地震地层层序模式,黄珏戴南组的储层结构为迷宫式,本次研究对油田后期开发调整具有指导意义。%The sequence stratigraphy of Dainan Formation were divided into two kinds of sequence boundary：the low angle onlap and high angle onlap by using three-dimensional seismic data.According to the activity level of the border fault,provenance,and A/S ratio,th
