复杂地层建模与三维可视化

Complex strata modeling and 3D visualization

提出了一种新的复杂地层建模方法。该方法先将离散的钻孔数据点分类,而后将不同类的离散数据点用径向基函数进行拟合;所生成的拟合曲面相交、裁剪得到地层的空间范围;由离散的数据点以及拟合插值点生成地层交界面格网,再经过计算机图形处理生成地层模型的三维图形。利用该方法对复杂地层建模,自动化程度较高、效果较好。

A new method for complex strata modeling is introduced. This method classifies discrete borehole data points; and then using radial basis functions to fit the discrete points of different kinds; the generated fitting surfaces are cut each other; then the strata space comes into being; at last,strata interface grids are created using discrete points and interpolation points; then 3D graphics of strata model is displayed after computer graphic processing. This method of complex strata modeling is highly automated; and the result is good.
