Summary:
As an important substitute area, the seismic character of the mound-bank bodies in mesa in the western area of Tazhong is infirm, different from the beaded strong and the moundy shape reflection of the reef-shoal reservoirs. Time-frequency is made analysis with generalized S transform, found the dominant frequency corresponding to seismic reflection feature of mound-bank reservoir in platform is 15-25hz, then a impedance inversion is made to the mound-bank bodies on the base of seismic pure wave data volume of 15-25hz , the recognizing accuracy of the mound-bank bodies in mesa is improved by the frequency-division impedance inversion.
