摘　　要：构造-岩性油藏地质条件差、油水关系分布复杂,经过长时间注水开发,使得该类型油藏剩余油分布规律更加难以描述,同时也对油藏下步挖潜的方向及调整方案的编制带来更大困难。在精细地质建模的基础上,综合考虑构造-岩性油藏地层沉积旋回、垂向非均质性及储量分布特征,对层内泥岩和干层进行特殊处理,建立描述该类型油藏剩余油分布的数值模拟模型。实例分析表明,建立的模型模拟小层含油饱和度分布及储量丰度分布与动态分析结果一致,可用于描述构造-岩性油藏剩余油的分布状况。Structural-lithologic reservoir is characterized by poor geological conditions and complex distribution of oil/water relations. Long-time development by water flooding makes it harder to describe the residual oil distribution of this type of oil reservoir.Moreover,it brings more difficulties to the further excavation of oil reservoir and the preparation of adjustment plan. On the basis of fine geological modeling,and considering cyclic sedimentation,vertical heterogeneity and reserves distribution features of structural-lithologic oil reservoir,intra-layer mudstone and dry layer are treated specially and the numerical simulation model is established to describe residual oil distribution in this type of oil reservoir. The case analysis indicates that,the distribution of oil saturation and reserves abundance predicted by the model is consistent with the results of dynamic analysis. Therefore,the model can be used to describe the distribution of residual oil in structural-lithologic oil reservoir.
