| 摘 要： | 三维油气运聚模拟计算方法需要在构造模型的约束下生成三维地质格架式网格。针对这一需求对现有网格生成方法进行了分析对比,并在此基础上提出一套三角形格架式网格生成方法。该方法采用了限定Delaunay三角剖分技术生成基础的地质层面模型,同时提出协同剖分算法来解决地层面网格在公共交线处的几何拓扑一致性问题,并表明了算法的正确性,最后给出地质层面的剖分实例。实验结果表明了该方法在工程实践中的有效性。

| Abstract: | The simulation method of three-dimensional hydrocarbon migration and accumulation process need to generate three-dimen-sional geological framework mesh.The generation of three-dimensional geological framework mesh is based on structure model con-straint.In response to this demand,the existing mesh generation methods are analyzed and compared,and on this basis a system for triangular framework mesh generation is presented.The constrained Delaunay triangulation algorithm is used to construct the geological la... |
