Abstract:Traditional wave impedance inversion processing and interpretation is on the basis of poststack migrated data,which can't meet the hypothetic conditions of wave impedance inversion. The paper uses AVO attributes parameters to detect the Pwave section and S-wave section, then implements wave impedance inversion separately. The paper discussed such key processing steps as how to do well the low-frequency component processing of wave impedance, compute the deconveltion factor and compute high-frequency component of wave impedance etc. This technique is used for real data processing and achieved evident effects.
