Multi-layer DEM Modeling and Application in Stratum Visualization based on IDL
Stratum 3D modeling and visualization technology is one of key and hot issues about 3D geological simulation research field. Borehole data is the main way to obtain required information about 3D stratum modeling. According to drilling data, the method of 3D stratum modeling based on multi-layer DEM is proposed. The method determines the sorting of stratum according to arrangement position of boundary stratum point in stratum drilling information and cross division of multi-layer DEM according to stratum lithology, thus form a 3D stratum framework that divides by lithology as element in 3D space. Considering that the layers of interpolation and fitting may occur pinch point phenomenon because the layers intersect, the sampling point detection algorithm is proposed and using the fourth-generation language visualization IDL implements a 3D stratum visualization system software.
