摘要(Abstract)：

以东营凹陷现河油区河146井区沙三中亚段湖泊相浊积水道储层为例,利用岩心、钻井资料及生产数据等,根据沉积体内部构型单元结构层次特征,将研究区浊积水道构型单元划分为七级,分别为层理、层理组、单一浊积水道内部侧积或加积单元、单一浊积水道、浊积水道带、浊积水道复合体及其组合,分析浊积水道储层构型特征及其对开发生产的影响。结果表明:研究区浊积水道储层构型以单一浊积水道为主,单一浊积水道宽度为120.0～450.0m,水道底部倾角为0.9°～2.4°;浊积水道厚度变化与延伸距离具有较明显指数关系,浊积水道侧向迁移明显;在古水流方向上投影距离小的注采井距生产效果较好;油水井位于不同单一浊积水道侧缘时,油水井间剩余油富集。该结果对浊积水道构型定量研究及开发对策调整具有指导意义。
