保边界平滑滤波方法在压制噪声的同时能够有效地保留地震同相轴局部变化的信息,现已成功地应用于地震数据处理中.本文以相干技术和数字图像处理中的图像分割合并技术为基础设计的保边滤波器,能够适应地震信号同相轴在局部小范围的三维空闻中近似为三维平面的特点,可确定适宜的滤波范围,从而对噪声实施较大幅度地压制,以提升滤波效果,有助于分析和识别所研究地质体中包含的断层、岩相和裂缝等信息.%In this paper the designing of the Edge Preserving Smoothing (EPS) is introduced, with EPS the noise in the seismic data can be removed while the details of the seismic events can be preserved, now this method is being used in seismic data processing. EPS filter which we designed based on coherence technology and splitting and merging technology in digital image processing can work well if the seismic event in small region of 3D space can be regarded as 3D plane, with EPS the suitable filter applying time window can be founded, so the noise can be greatly reduced, better filtering results can be obtained and the fault, channel and fracture can be easily distinguished and delineated.
