In consideration of the problem of lower precision of horizon calibration and interpretation,structural interpretation,reservoir inversion ,according to the forward modeling theory,the major reason resulted from the difference between the seismic wavelet dominant frequency and practical seismic wavelet dominant frequency,was the lower quality of synthetic seismogram.However,based on the modeling theory,the dominant frequency of seismic wavelet and practical dominant frequency of seismic wavelet and their difference of relationships were all induced by the disagreement.Furthermore,the dominant frequency of accurate seismic wavelet would be obtained because of the difference of relationships,thus the synthetic seismogram of higher quality is achieved with this kind of dominant frequency wavelets.
