Comparative study of main deconvolution methods on sismic data

摘要

In this paper we treat a problem which occurs in différent domains : geophysics, speech processing, echography, where the goal isudto characterize a propagating medium through its impulse response from a filtered and a noisy one .udIn seismic reflection a wave named source wavelet is emitted into the earth to detect reflections at the interfaces of geologicudlayers. The records or seismic traces may be considered as the linear filtering resuit of the wavelet by the earth response orudreflectivity function .udDeconvolution lies ln estimating the wavelet, removing its affect from the trace in order to restore the reflectivity .udWe present a comparative study of différent methods with simulations representing numerous situations to do more in thatuddomain and to define a strategy in seismic data processing .
