The Extractive Method of Seismic Wavelet in Different Time Window and the Application in Synthetic Seismogram

Synthetic seismogram is an important ligament of seism and geology and its precision straightway affects the calibration of the seismic geologic horizon. A key problem of synthetic seismogram is the problem of wavelet. The paper advances the extractive method of seismic wavelet using the seismic data and log information, the extractive method of seismic wavelet in time windows. Also, the method is applied in synthetic seismogram and achieves good effect in two facets, improving the resolution power and the degree of fit seismic section. The paper describes the method in detail and offers the analysis of model and example.
