Abstract:

Seismic coherence cube technique can efectively reveal the lateral changes of strata,such as fault and complex structure．But when the original seismic data volume has 1ower signal to noise ratio，the resolution of the coherence cube is poor because of the influence of the noise．In order to improve the resolution，the edge preserving smoothing(EPS)algorithm is applied to the calculation of the coherence cube，which carries out the processing of edge preserving smoothing to the original seismic data volume before the calculation of the coherence cube．The computing resuh shows that the method could efectively improve the ability of the coherence cube to distinguish the fault from complex structure．
