Abstract: The acoustic impedance inversion based on wavelet edge analysis modeling (AIW) can take both well-logging acoustic impedance and seismic attributes from seismic data as restrictions to build initial inversion model, thus avoiding bad influence brought by inaccurate initial model due when using conventional inversion methods and improving accuracy of inversion. The results show higher resolution and well match with the well data.

Key words: acoustic impedance, inversion, restriction, wavelet
