结合实例，运用地震解释、测井解释、岩心分析等资料，依据相控建模思路，依次进行储层构造、沉积微相、储层物性的建模。重点进行了模型检验和评价及储层非均质性分析。通过对双河油田Ⅶ油组建立储层物性模型，分析研究结果表明：双河油田Ⅶ油组是高孔高渗油藏，总体横向和纵向非均值性也都较强，建模结果符合地下地质体实际情况，为油田的动态开发提供了充分的科学依据，从而说明储层相控随机建模技术能够满足更加精细的油藏描述应用要求。

This paper successively constructs the structural model,sedimentary micro-facies model and reservoir physical model of the Ⅶoil group in Shuanghe Oilfiled by using the data of seismic interpretation,well log interpretation and core analysis. The main point is to verify the model and analyze the reservoir heterogeneity. The model analysis results indicate that the Ⅶoil group has high horizontal and vertical heterogeneity,high porosity and permeability. The model accords with the actual situation of the subsurface geologic body,which can provide the scientific basis for dynamically developing oilfield and meet the demand for applying the fine reservoir description technology.
