基于SKUA的浅层三维地质建模方法与实例研究

SKUA-based Shallow Three-dimensional Geological Modeling Method and Case Study

三维地质模型能够以三维的形式表达复杂的地质结构和地质体形态,并有效地应用于工程地质、油气开发、地质灾害治理、地球物理勘探等领域。论文回顾了三维地质建模的历史背景,针对工程区地质分层较好但钻孔数据不足的情况,提出结合空间插值拟合技术进行快速建模的方法,并参考地震勘探地质解释剖面进行地层面的调整,可视化效果较好,该模型可用于设计特殊地质体的正演模拟,得到地震响应特征。

Three-dimensional geological modeling can express complex geological structures and geological body forms in 3D form,and are effectively applied to such as engineering geology,oil and gas development,geological disaster management,geophysical prospecting etc.This article reviews the historical background of three-dimensional geological modeling,In view of the good geological stratification in the engineering area but insufficient drilling data,a fast modeling method combined with spatial interpolation fitting technology is proposed,and the ground level is adjusted with reference to the seismic exploration geological interpretation section.The visualization effect is good,the modeling can be used to design the forward simulation of special geological bodies,and obtain the corresponding characteristics of the seismic.
