基于钻孔数据的含断层地质体三维建模方法

3D modeling method of geological bodies including faults based on borehole data

提出了一种构建含断层地质体三维模型的新方法。该方法以广义三棱柱作为建模的基本体元,根据钻孔数据的特点和知识推理规则,进行断层等复杂地质构造的推理和自动建模,避免了不必要的人为干预,扩展了钻孔数据建模的适用范围和表现能力。最后,通过研究实例展示该方法的实际建模效果。

A new method to model 3D geological bodies including faults is presented.This method takes generalized tri-prism （GTPI as primitive modeling dement,realizes inference and automatic modeling of geological structure including faults according to characteristics of borehole data and the knowledge inference rule,which can avoid unnecessary manual intervention, extend applicable range and expressing capability of 3D geological modeling.Finally,the practical modeling effect of this method is shown in a case study.
