摘要： A system and method for modeling a subsurface structure. Data representing a configuration of faults, horizons, and/or unconformities may be transformed to a depositional model comprising cells representing an estimated configuration of subsurface structure at a depositional time period when the subsurface structure was formed. Groups of cells in the depositional model may be divided into sub-meshes using iso-surfaces, where one set of iso-surfaces may represent the horizons at the depositional time period. The sub-meshes may be divided into one or more parts using the transformed geological data representing an estimated depositional configuration of the faults. For each group of cells in each sub-mesh part, the group of cells in the sub-mesh part may be represented by a single polyhedron. The polyhedrons may be transformed to generate a current model to represent the current configuration of the faults and horizons using transformed polyhedrons.

摘要翻译： 一种用于建模地下结构的系统和方法。 表示故障，层位和/或不整合的配置的数据可以被转换成包括表示在形成地下结构的沉积时间段的地下结构的估计构型的单元的沉积模型。 沉积模型中的单元组可以使用等面分割成子网格，其中一组等面可以在沉积时间段代表层次。 可以使用表示故障的估计沉积构造的变换地质数据将子网格划分为一个或多个部分。 对于每个子网部分中的每组细胞，子网部分中的细胞组可以由单个多面体表示。 可以转换多面体以产生当前模型来表示使用变换多面体的故障和层位的当前配置。
