高邮凹陷富民油田戴南组震积岩特征

Seismite in the Dainan Formation of the Fumin Oilfield in the Gaoyou Depression

高邮凹陷富民油田戴南组沉积时期,受到中-新生代构造运动的影响,古地震活动强烈,在岩心的观察过程中发现了很多震积岩构造,例如液化砂岩脉、阶梯状小断层、震皱岩等。通过对其单井垂向特征的观察和研究,总结前人的研究成果,得出了研究区的震积岩垂向序列,并得出古地震作用下的碎屑流沉积普遍发育在震积构造的顶部的结论。

Sedimentation of the Dainan Formation in the Fumin oilfield, Gaoyou depression was accompanied by strong seismic activity which resulted in many seismite structures such as liquefied sandstone veins and stepped small faults and so on. This paper deals with seismite vertical sequence and debris flow deposits on the top of seismic sequence system.
