摘要 分析了Steerable Pyramid分解用于断层检测的基本原理.输入的三维地震时间切片经过Steerable Pyramid分解后,不仅可以分析不同尺度不同方向上断层的特征及走向,还可以通过重构得到断层信息.该信息不仅是断层的边缘检测,而且将断层直接提取出来.在去除了断层信息后,该方法还可用于河道砂的沉积成像.将该方法应用于一张实际的地震振幅属性切片,结果证明将Steerable Pyramid分解用于储层断层检测与沉积成像是成功的.但是,处理结果对空间平滑参数都很敏感,参数的最优选择要根据输入图像的特征而变. The basic principle of decomposition and construction of Steerable Pyramid used to detect faults was given a detailed introduction. The characteristics and distribution of faults in different scales and directions after the decomposition of Steerable Pyramid were studied and faults information obtained through a re-construction. The information was not only concerned with the edge detection of fault, but also enhanced the fault itself. The images of channels were obtained after the faults were wiped off. It is proved that using Steerable Pyramid to detect faults and channels is a successful method. But the effect is susceptible to smoothing parameters, which should be selected based on the characteristics of the inputting figure.
