摘　　要：储集层的微相砂体几何规模特征及分布规律是分析地下油水运动规律和调整注采井网的基础。为了满足油田开发后期预测剩余油分布的需要,根据双河油田地质条件提出了扇三角洲前缘储集层精细骨架模型建立方法。精细骨架模型是建立在沉积学原理、微相砂体识别标准、微相砂体分布规模、河道密度和特殊砂体的形成条件等地质研究基础上的,然后综合运用各种地质知识确定微相砂体的边界和内插微相砂体。通过解剖双河油田小井距资料建立了微相砂体的宽度与厚度的关系和河道发育定量规律,并建立Ⅳ油组2小层骨架模型。提出的方法对其它同类油田的储层精细描述具有重要的借鉴意义。The geometrical scale and distribution of a reservoir's microfacies sand body are the bases to analyze the regulation of in-situ oil and water flow and adjustment for proper well patterns. This paper proposes a method to build the detailed framework model for fan-delta front reservoir based on the geological features of Shuanghe oil field, in order to meet the requirements of predicting the remaining oil distribution during the late period of development. Before setting up a detailed framework, the geological knowledge such as the depositional mechanism, the distinguishable criterion, the scale of microfacies sandbody, the channel density and the occurring conditions of specific sandbodies, etc. are needed to determine the borders of microfacies sandbodies and interpolation for them. In this paper, the width-thickness relationship of microfacies sandbodies and the quantitative description of the channel development are presented, and the framework model for Layer-2 in oil member Ⅳ is developed. Such a method could be significant for the detailed reservoir description of other analogous oilfields.
