Indicator principal component microfacies simulation is a technique for describing lithofacies or microfacies distribution using sequential indicator simulation method based on selection of principal components with discontinuous variables.The method is fast and convenient in operation by using more original information.Based on the geological knowledge about reservoir,a 3D microfacies model of unit S II 7+8 fluvial sandbody of study area was developed with the indicator principal component simulation method.Compared with the conventional 2D microfacies model,the 3D model can show the fluvial sandbody constitutes in the vertical direction,and the distribution of flow units in 3D space.The technique is useful for detailed reservoir description and potential study of Daqing Oilfield in the later period of high water cut.

指示主成分模拟是在提取不连续变量主成分的基础上 ,采用序贯指示方法模拟岩相、沉积微相的分布。该方法具有快速、实用的特点 ,并使用了更多的包含在原始数据中的信息。以储层地质知识库为基础 ,采用指示主成分模拟方法建立了研究区内萨Ⅱ7+8单元微相三维空间分布模型。与以往研究二维微相制图结果相比较 ,所建立的三维微相分布模型较好地揭示出河流相储层按上、中、下 3套砂体及砂体空间分布的变化规律。充分说明了三维建模在揭示砂体空间非均质性方面的巨大优势 ,对于指导目前大庆油田高含水后期储层精细描述和潜力分析研究有实际意义
