| 摘 要： | 对相邻钻孔数据的类型进行了分析,对不同连续性和规则性的地层分界面进行了建模.考虑地层分界面的光滑性和整体控制性,运用边界表示法(B-Rep)和B样条曲面重构地层分界面,为地层建模提供了一种新的方法.建模研究表明:在钻孔数据前处理算法的基础上,B-Rep能够建立连续型、非连续型、空洞型等任意边域的地层分界面.

| Abstract: | Through the analysis of relation of neighborhood bore-hole data,horizon interfaces with various complex boundaries were reconstructed by boundary representation(B-Rep) method considering the smoothness of the surface and the feasibility of modification.A modeling method of reconstruction was proposed with 3 degree B-Spline surface,which was a new method for horizon interface reconstruction with arbitrary boundary in engineering practice.The modeling researches showed that B-Rep method and B-Spline surface c... |
