Application of diffusion filtering method to the seismic data processing
Online published: 2014-02-05
Based on anisotropic diffusion filtering equation, this paper presented the corresponding numerical equation, together with its simplest anisotropic diffusion filtering numerical equation. Then, we applied diffusion filtering method to four aspects of application, such as multi-scale low-frequency reverse-time migration noise suppression, seismic reflection wave and scattered wave relatively separating processing, holding fault boundary random noise suppression and pre-stack and post-stack seismic data interpolation processing, and also presented each assumed condition of the applications. The computation results show that the diffusion filtering method can be used to obtain good processing results under different assumed conditions and instruct the practical seismic data digital processing.
