摘要: 复杂地质体几何模型的建立是油气勘探开发领域的一项重要工作,在介绍目前地质体几何建模方法的同时,分析了表面建模方法与实体建模方法相互之间的融合趋势,提出了一种基于三角网格模型的整体建模过程,并在地质体层面三角网格模型的基础上,提出了一种改进的半边数据结构,给出了一种三维地质体闭合区块结构的构造算法,该算法为进一步的地质体实体模型的建立奠定了基础,并且可应用于地震正演模拟计算,射线追踪和三维地质模型可视化等领域.

Abstract: Building geometry model of complicated geological entity is important work in exploration and exploitation oil and gas field. With the introduction of geological geometry modeling method, the trend of syncretizing the surface modeling and solid modeling was pointed out, and an integral modeling method based on the TIN model was presented. Data structure of geological block was presented based on improving on half-edge data structure, and the algorithm of constructing coherent 3D geological blocks from completed stratified geological structure and some results was presented. The algorithm is very useful for building the solid model of geological structure and also can be used in several actual projects of forward modeling, ray tracing method and visualization of 3D geological model.
