Abstract

Summary

Seismic coherence is a convenient and effective technique for characterizing the morphology of stratigraphic discontinuities which has been widely used in seismic exploration. The method based on semblance is widely practiced by researchers for its simple and effective. As an energy ratio attribute, it can be also thought as the squared correlation of windowed seismic data with a constant. In this paper, we will demonstrate a class of new semblances that are higher order semblances which are actually the ratios of different norms. As an extension of traditional semblance, they have a better characterization of faults which is due to the extension of data frequency that the weak discontinuities come to be enhanced. According to higher order semblances, we realize an accurate cognition of the fracture mod from a local region in Bohai Bay Basin.
