    • The pore structure of rocks and other materials can be determined through microscopy and subject to digital simulation to determine the properties of multiphase fluid flows through the material. To conserve computational resources, the simulations are preferably performed on a representative elementary volume (REV). The determination of a multiphase REV can be determined, in some method embodiments, by deriving a porosity-related parameter from a pore-matrix model of the material; determining a multiphase distribution within the material's pores; partitioning the pore-matrix model into multiple phase-matrix models; and deriving the porosity -related parameter from each phase-matrix model. The parameter's dependence on phase and saturation can then be determined and analyzed to select an appropriate REV size.
    • 岩石和其他材料的孔隙结构可以通过显微镜来确定,并进行数字模拟,以确定通过材料的多相流体流动的性质。 为了节省计算资源,模拟优选地在代表性基本容积(REV)上进行。 在一些方法实施方案中,可以通过从材料的孔 - 矩阵模型中导出与孔隙度相关的参数来确定多相REV的确定; 确定材料孔内的多相分布; 将孔矩阵模型划分为多个相位矩阵模型; 并从每个相位矩阵模型推导出与孔隙度相关的参数。 然后可以确定和分析参数对相位和饱和度的依赖性,以选择适当的REV大小。
