Depositional system and sand body distribution in the third member of the Yanchang Formation in the Yijun area in the southern Ordos Basin

  • 摘要: 鄂尔多斯盆地南部是重要的石油产出区域,盆地南部宜君地区上三叠统延长组长3段为主要含油气目标勘探层位。基于对该区内大量钻井、测井及三维地震资料的研究,通过阴极发光、地震前积体倾向及倾角换算等方法,并结合前人的研究成果,对该地区的物源体系进行了系统地分析,认为该区晚三叠世主要受南部渭北隆起物源的影响。长3沉积时期该区的沉积体系发育,砂体展布受物源控制,主要发育辫状河三角洲前缘沉积,其中水下分流河道和河口坝砂体为良好的储集岩类型。在此基础上,对长33—长31各沉积期砂体分散体系及沉积相的平面展布特征进行研究,为储层有利区带预测提供良好的沉积学理论依据。
