摘要
建立盆地三维构造 -地层格架是进行三维盆地模拟的关键技术之一 .为了使一系列二维地震解释剖面转化为盆地的三维构造 -地层格架 ,必须选择有效的内插外推方法 ,而插值方法的选择和空间分析的实现依赖于空间拓扑结构 .在探讨基于B_Rep模型的盆地三维空间拓扑结构表示法及图形编码准则的基础上 ,引进了适合于构建盆地三维构造 -地层格架的几种形态插值方法 ,并提出了一种新的方法———相似变形插值法 .这些方法曾成功地应用于珠三盆地三维构造 -地层格架的模拟 。
Establishing 3_D tectonic_stratigraphic basin framework is one of the key techniques in the 3_D basin modeling. Effective interpolation and extrapolation methods must be chosen to convert a series of 2_D seismic interpretation profiles into 3_D tectonic_stratigraphic basin framework. However, the selection of interpolation method and realization of spatial analyses depend on the spatial topological structure. In line with the B_Rep model_based 3_D spatial topological basin structure and the corresponding coding graphical principle?, several kinds of morphological interpolation methods are introduced in this paper for the reconstruction of 3_D tectonic_stratigraphic basin framework: linear interpolation, polynomial interpolation, Kriging interpolation and spline interpolation. At the same time, the similarity deformation interpolation method is also proposed. All these methods, once successfully applied to the simulation of the 3_D tectonic_stratigraphic basin framework in Zhusan basin, may well support various spatial analyses such as vector shear analysis.
