| 摘 要： | 针对三维薄层地层结构的形状特点，提出了一种利用类三棱柱网格构造三维地质模型的方法。该方法利用三角网格参数化在地层面三角网的基础上重建类三棱柱网格模型，避免了现有类三棱柱建模方法中切割三棱柱的复杂计算。同时给出了一种在类三棱柱网格模型中通过插入井分层点的小层三角网格来生成多层类三棱柱网格的模型细化方法，最后通过建模实例对方法进行了验证。

| Abstract: | On account of the special thin stratum in the petroleum prospecting area,this paper puts forward a 3D geological modeling method based on analogical tri-prism grid.This method avoids the complex computing of cutting tri-prism in current methods by parameterization of surface triangulations.It also puts forward a refinement method of the modeling by inserting the small layer triangle grids based on analogical tri-prism model.The instance has shown the result of these methods. |
