摘　　要：本文介绍一种合并三维地质模型网格数据体的新方法。在油藏描述过程中，三维地质建模一般产生几十万至几百万个网格数据体，要将其用于数值模拟，需对网格进行粗化（Ｕｇｓｃａｌｉｎｇ）。本文研制的粗化模型不同于体积加权平均合并网格数据方法，它是考虑流体在油藏中的流动特性，采用Ｄ４高斯求解渗流力学方程，解决网格数据合并问题，此法能结合数值模型特点，解决断层封闭性描述及有关物性参数问题。This paper presents a new scale-up technique for the grid data volume of a 3D geological model.In the description of a reservoir, grid data volume created from the 3D geological model has a grade of 105 to 106, which are needed to be scaled-up for numerical simulation. The upscaling method which differs from the general volumetrically weighted average is used in the upscaling model written in this study and the flow properties of the reservoir fluids are involved. This new technique can solve the problem of upscaling grid data with D4 Gauss equation for the percolation mechanics and that of describing the sealing property of fault and the relevant parameters of physical properties with the feature of the numerical simulator.
