地层作为三维地层模型的一个重要概念,在三维地层模型的建立中起着关键作用。如何以岩性来刻划这些层面就显得非常重要了。根据地质钻孔资料中岩层分界点的排列,确定地层的排序。根据多层DEM建模的概念,按岩性对多层DEM进行了交叉划分处理。形成空间中严格按照岩性为要素进行划分的三维地层模型的骨架结构。
As an important concept of 3D stratigraphic model, strata play a key role in the establishment of 3D stratigraphic model. How to characterize these aspects with lithology is very important. According to geological drilling data in the demarcation point arrangement, to determine the rank of strata. According to the concept of multi-layer DEM modeling, multi-layer DEMs are divided by lithology. Form the skeleton structure of 3D stratum model which is divided strictly according to lithology as the element in the space.
