南堡凹陷高南地区东一段沉积微相的刻画

高南地区自1986年以来已先后全面投入开发生产;近年来,在高南地区加大前期研究,该区中浅层是油田开发产能建设重点含油层位,具有较大的扩边建产潜力。为了更好的了解砂体特征,也为了可以为后期的储层评价奠定基础,对南一段沉积微相进行了刻画。在区域地质背景条件分析基础上,首先开展了单井岩心相分析;继而开展单井测井相分析;并结合地震属性特征,以砂岩组、小层为研究单元在平面上划分沉积相带,以砂组为单元绘制了沉积优势项相平面图。

The sedimentary microfacies characterization of Dongyi Formation of Gaonan Region,Nanpu Sag

Since 1986 Gaonan Region has been put into production entirety.In recent years,the initial study has been increased.The main oil-bearing formation of this region is the shallow layer which has a larger extension production potential.For the purpose of understanding the characteristics of sand bodies betterly,and laying the foundation for reservoir evaluation,the sedimentary microfacies of Dongying formation was given.First,single well core facies was made,then single well logging facies analysis was slso given.Latterly sedimentary facies in the plane was devided that use the sandstone layer and single layer as research unit.Finally,the sedimentary advantage phase was made .
