摘　　要：围绕油藏数值模拟过程中三维地质模型的建模技术进行了分析与探讨,详细介绍了基于角点网格模型的建模方法,给出了相应的实现步骤。其主要流程是:首先根据断层数据构造断层模型,在断层模型的基础上构建骨架模型;然后在骨架模型约束下采用地层恢复技术实现含断层的地层模型;最后基于结构模型插值物性参数完成属性模型。以塔河油田缝洞型油藏为例,对建模流程和技术的可行性进行验证,结果表明,其建模结果与专业地质建模软件Petrel相符。The authors analyze and discuss the modeling technique of 3Dgeomodeling in the process of numerical reservoir simulation,introduces the detailed modeling method based on corner-point grids model and gives the corresponding implementation steps.The main process is to：construct the fault model according to the fault data;bulid the pillar gridding model based on the fault model;complete the layer which bares the fault based on the pillar gridding skeleton model through,adopting the layer recovery technique to complete the layer that contains fault;and further,accomplish the building of the property model according to the interpolation of physical property parameters based on the structural model.Finally,by takeing the fractured-vuggy reservoir of Tahe oilfield as an example,we validate the modeling process and technology.
