摘　　要：随着计算机技术的和精细地质建模的发展,油藏描述由传统用平面等值线来描述发展为三维立体网格描述,油藏描述趋向于网格化。但一般地质模型网格数量多、数据量大,现有的计算机计算速度都无法满足将这些地质模型直接导入数模软件中进行数值模拟,所以模型粗化是解决这一问题的有效途径,本文将阐述集中模型粗化方法。With development of computer technology and fine geological modeling, the reservoir description converts from the traditional contour to three-dimensional grid description, the reservoir description tends to meshing. General geological models need a lot of number grids and data, existing computer computation speed cannot meet the demand of numerical simulation by directly introducing these geological models into numerical simulation software, so model coarsening is an effective way to solve this problem. In this paper, several model coarsening methods were discussed.
