本文建立了一裂缝性油藏三维油、水两相的渗流模型。采用双孔隙度、单渗透率的渗流微分方程组描述裂缝系统和基质系统中流体的流动。与以往不同的是，应用有限元方法进行差分离散，并将油、水井视为单元的边界进行处理，选用任意形状六面体（曲边）单元和等参元变换以及隐式压力和隐式饱和度交替求解的方法。文中还给出了本模型对Ｋａｚｅｍｉ算例的计算对比结果。
In this paper, a three-dimensional oil and water seepage model of fractured reservoir is established. Percolation differential equations with dual porosity and single permeability are used to describe the fluid flow in the fracture system and matrix system. Different from the past, finite element method is used for differential discretization, and oil and water wells are treated as the boundaries of the unit. Arbitrary hexahedron elements and isoparametric elements transformation are used, as well as implicit pressure and implicit saturation Alternative solution. The paper also gives the calculation results of the Kazemi case by this model.
