一种断层多边形自动平滑方法

A Fault Polygon Extraction and Smoothing Method

提出了一种断层多边形平滑方法.该方法针对利用边界追踪算法提取断层多边形,利用断层多边形折线之间的角度,边长等因素,在保持断层多边形形态的前提下对断层多边形进行平滑,改善了断层多边形的视觉效果和美观,为地震资料解释提供了一种很好的方法.经过大庆油田多地区地震图像的验证,此断层多边形提取与平滑方法可以有效提取出断层多边形并去除断层多边形的毛刺,对断层多边形平滑效果显著.

A method for fault polygon extraction and smoothing is proposed in this paper. The method extracts fault polygon by boundary tracking algorithm, it uses the angle of fault polygon line and side length to smooth polygonal fault under the premise of keeping fault polygons form, and then enhances the fault polygon visual effects and aesthetics, it also provides a very good method for seismic data interpretation. After the validation in daqing oilfield seismic image, this fault polygon extraction and smoothing method can effectively extract fault polygons and remove the burr of fault polygon, the effect in fault polygon smooth is remarkable.
