一种三维地震反射面自动追踪算法及其应用
|
摘要
针对获取构造图的传统方法存在效率低、易发生串层位的现象,提出一种基于优化理论的反射面自动追踪算法.该算法不需要通过烦琐的追踪和对比就可快速确定反射面形态和结构,并能输出反射面上各点的三维坐标,有效避免追踪过程中发生串层位现象,可提高结果的可靠性.
One of the purposes of the seismic data interpretation is to automatically generate structural map.The traditional methods are the same event track and contrast on a series of cross-cutting seismic profiles,then through space correction to get the structural map.This paper presents a reflecting surface automatic track algorithm based on optimization theory.The algorithm can quickly identify the reflecting surface shape and structure without cumbersome track and output the three-dimensional coordinate values of reflecting surface points.It can avoid the series layer phenomenon in the tracking process effectively and improve the reliability of the results.
