摘　　要：为了解决高分辨率层序对比时较难识别短期基准面旋回的问题,提出了应用多种信息和对比手段的小层综合对比方法。在油藏范围内进行短期层序对比时,由于受到各类自旋回沉积、地层侵蚀和缺失、沉积微相空间变化等复杂因素的影响,因而对比难度会增大。并根据地层特点,对各类方法进行选择,提出了在高分辨率框架内,采取沉积自旋回对比、关键界面约束对比、河流切割和充填对比、储层流体性质对比和沉积微相相序对比等多种对比相结合的方法。将新的对比方法应用于苏丹Palogue油田的小层对比,取得了较好效果。In order to improve sub-layer correlation with high-resolution sequence and recognize the short base level cycle, an integra ring method based on sequence stratigraphy was proposed. The strata correlation could be confused by autocyclicity sediment, erosion and loss of layer, and dimensional diversity of micro-facies, which resulted in the difficulty of strata correlation. A strata correlation method by integrating autocyclicity sediment correlation, key surface correlation, corrading stream correlation, reservoir fluid correlation and microfacies sequence correlation was presented and successfully applied in Palogue Oilfield of Sultan. The results show that this method is correct and effective to sub-layer correlation.
