摘　　要：在地震属性预测砂体约束条件下,利用老油田丰富的钻井、取心、测井、试油试采及多年的生产动态数据,对Ⅳ2层沉积结构再认识,纵向上细分流动单元,平面上划分沉积微相,修正原来的窜层现象,运用陀螺资料开展顶面微构造认识,建立油藏精细地质模型.在合理劈分油水数据的基础上,利用Eclipse油藏模拟软件定量研究剩余油分布,再结合生产动态进行修正,从而提高剩余油认识深度.结果表明:高含水期厚油层仍有较大潜力,可分区分类采取井网调整、提液、改变液流方向等综合调整,预计采收率可提高5.4个百分点.This paper,under constraint condition by seismic attributes to predict sand,having used such as drilling,log,well test and long-term production performance to re-understand Ⅳ2layer deposition texture,subdivide flow units vertically,divide sedimentary micro-facies, modify scurrying layer before.By gyro data,analysed the top microtectonics,and built the detailed geological model of reservoir.On the basis of reasonable data on water splitting,by using the Eclipse reservoir simulation software,quantitative research remaining oil distribution was studied,combined with the production dynamics,leading to improved understanding of the depth of the remaining oil.The results showed that：At high water cut stage,thick oil layer still has large potentiality,and comprehensive adjustment of taking pattern adjustment,extracts,changing the flow direction for different classification and zones,recovery is expected to be an increase of 5.4percentage points.
