| 摘 要： | 三维数字地层格架自动生成技术研究是对地质体三维自动建模的初步探讨。基于钻孔资料,通过数字化、三角剖分,地层对比等数值计算与非数值计算,把建模生成分解为垂直地层界面伸展方向与平行地层界面伸展方向两个相互独立的过程,采用线性插值法先自动模拟生成地层格架元,再依据格架元之间的数值关系进行模型整合形成地层格架体。

| Abstract: | The research of automatic modelling on three-dimension (3D) digital stratigraphic framework is a preliminary approach to the 3D automatic modelling of geologic bodies. Based on doring data, the automatic modelling was divided into two processes independent each other in the perpendicular and parallel directions of stratigraphic interfaces by numerical and non-numerical calculation such as digitization, trigonometric division and stratigraphic correlation. At first, linear interpolation was used to model stratigraphic framework cells automatically. Then, the models of framework cells were conformed according to numerical relations among them so as to form stratigraphic framework bodies. |
