摘要
依据岩心观察、测井资料解释和砂体的展布特征对沉积相进行了综合分析,认为饶阳凹陷馆陶组为河流相沉积体系,其中馆陶组底部为辨状河,馆陶组中上部为曲流河。平面上,两种河流相沉积类型在饶阳凹陷都广泛分布,河道一般呈北北东向带状展布;剖面上,辨状河河道砂体相互叠置,曲流河河道砂体呈孤立状分布。
Based on the core observations、logging data interpretation and the distribution characteristics of sand body,we have taken a comprehensive analysis to sedimentary facies,inferring that Guantao Formation of Raoyang Sag is stream depositional system.The lower segment of Guantao Formation is braided stream.In the plane,two kinds of fluvial sedimentary systems are widely developed in the study area and the river channel shows a banding distribution in NNE;In the section plane,the braided stream channel overlay each other and the meandering stream channel is isolated.
