摘要：
应用河流砂体构型理论，首先识别出单个心滩坝，并对单个心滩坝进行构型解剖，建立了心滩坝的三维构型模型。从砂体构型的角度阐明了储集层初始含油气性差异的成因，解决了该区油水关系矛盾突出的问题。指出在厚砂体连片分布的单个沉积时间单元内，河道的侧向迁移可使不同期叠置砂体各自具有独立的流体系统；在同一河道内，心滩坝砂体与河道充填砂体之间的构型界面也会使不同成因砂体不完全连通，导致含油级别不同；成因砂体内部界面也能使界面上下含油饱和度及油水界面等存在较明显差异。
Abstract:
Based on the theory of fluvial sandbody architecture, the single beach bar was identified and its architecture was analyzed, then the 3D architecture model was built. The discrepancy of the hydrocarbon distribution was present from the angle of sandbody architecture, and the contradiction of oil and water distribution was resolved. In the single depositional time unit in which the thick sandbodies were widely deposited, independent fluid systems may exist in the overlaying sandbodies due to the lateral migration of the channel. Also, in the single channel, the incomplete connectivity and the discrepancy of oil-bearing grade of different sandbodies were caused by the bounding surfaces between the beach bar and the channel fillings sandbodies. Furthermore, the oil saturation and the oil-water interface had considerable difference between wells even in the single mid-channel bar due to the internal bounding surface of the sandbodies.
