Application of Acoustic Impedance Inversion Technique to SWJZ Oil Field in Songliao Basin

Inversion acoustic impedance is one of the inversion of lithology.The aim of the acoustic impedance inversion is to trace and predict reservoir.To rebuilt the characteristics of reservoir is the main seismic inversion technique by now.The expected resolution of inversion results in this thesis is higher than seismic section's,meanwhile the relationship between each layers is clearer and the physical property of layers is much more informative which indicates the traverse changing of lithology and lithofacies.
