摘　　要：曲流河点坝构型很大程度上控制了点坝中剩余油的空间分布,是特高含水期剩余油挖潜的重要研究对象。本文以港东油田A区块的明化镇组为例,在九级构型研究基础上,对曲流河点坝储层构型进行了解剖,描述了侧积层的几何形态、规模、方向及其叠置关系;定量识别了侧积层的个数、倾角等构型要素;并且,利用曲流河侧积层的测井曲线判别结果,运用基于面的确定性建模方法,实现多个侧积层面的空间表征,建立了精细的点坝沉积单元构造模型、点坝及侧积层模型,为后续剩余油分布的研究奠定基础。The configuration of point dams in the meandering river largely controls the spatial distribution of remaining oil in the point dam,which is an important research object for the potential exploitation of remaining oil in ultra-high water-cut periods.Taking Minghuazhen Formation in Block A of Gangdong Oilfield as an example,and based on the study of nine-level configuration,this paper dissects the reservoir configuration of the meandering river point bar and describes the geometry,scale,direction and superposition relationship of lateral deposits.The configuration elements such as the number and dip angle of lateral deposits are identified quantitatively.In addition,by using the results of the logging curve of lateral deposits in meanders river and the surface-based deterministic modeling method,the spatial characterization of multiple lateral deposits is realized,and a fine structural model of the point dam sedimentary unit,and the models of point dam,and lateral deposits are established,which lays a foundation for the subsequent analysis of residual oil distribution.
