ITERATIVE DIP-STEERING MEDIAN FILTER FOR SEISMIC DATA PROCESSING |
摘要 |
An iterative dip-steering median filter is provided for random noise attenuation in seismic data where conflicting dips are indicated in the data. A number of dominant dips inside a processing window or sample of the data are identified by a Fourier-radial transform in the frequency-wavenumber domain. A median filter is then applied along the dominant dip to remove noise, and the remaining signal after filtering is retained for further median filter iterations. Iterations are repeated to apply the median filter along the most dominant dip in the remaining data. The processing continues in subsequent iterations until ail selected dips have been processed. The remaining signal of each iteration is then summed for final output. |
