基于钻孔数据的自动化地质体三维建模研究

Research on Automated Geological 3D Modeling based on Borehole Data

本文基于利用地质钻孔数据实现自动化地质三维建模角度出发,研究了现有的三维地质建模算法并对比其优劣进行了分析。目前国内外共存在20余种三维空间地质体建模方法,其中多层DEM结构建模法、广义三棱柱法建模方法较其他方法更为精确;针对地层中可能出现的地层缺失、尖灭、断层等问题基于广义三棱柱法算法提出了优化方案。

Based on the use of geological borehole data to realize automatic geological 3 D modeling, this paper studies the existing 3 D geological modeling algorithms and compares their advantages and disadvantages. The main conclusions are as follows: There are currently more than 20 types of 3 D geological modeling methods at home and abroad, among which the multi-layer DEM structure modeling method and the generalized triangular prism method are more accurate than other methods. An optimization scheme of the algorithm proposes of the generalized triangular prism method is proposed for problems such as stratum missing, pinching, and faults that may appear in the stratum.
