There are many methods for seismic impedance inversion. Aiming at the methods of generalized linear inversion , the key techniques are discussed here , such as iterative impedance inversion , regularization method , resolution of impedance inversion , the statistic and mean square deviation used to control the inversion quality , secondary smooth filtering and the constrained impedance inversion. And a great of modeling computation are carried out . Referred to the methods of recurrence impedance inversion , the main techniques are analyzed in the aspects of the wavelet and reversed wavelet extraction , the effect of noise on reversed wavelet extraction and so on.
