摘要
将扩散滤波方法引入地震数据处理领域,给出了三维各向同性和各向异性两种扩散滤波方法的基本原理。开发了相应的地震数据处理模块:Ckydiffusion,详细分析了该模块的设计思路,指出了模块中的关键参数。在实际三维地震资料数字处理(如随机噪声压制、低频逆时噪声压制等)中取得了较好的应用效果。
The diffusion filtering method is introduced into seismic data processing domain, the 3D isotropic and anisotropic diffusion filtering methods＇ fundamental principles are presented, the corresponding seismic data pro-cessing module, called as Ckydiffusion, is developed, then the designing idea of the module is analyzed in details, and the key parameters are pointed out. The results show a good application of the practical 3D seismic data numer-ical processing, such as random noise suppression and low-frequency RTM noise suppression.
