Based on elastic impedance inversion theory, a new AVO approximation was derived and a new elastic impedance equation involving Possion’s ratio parameters was proposed. The results show that elastic impedance inversion by using the new AVO approximation can directly obtain Possion’s ratio, which reduced cumulative error, and improved the stability and anti-noising ability, moreover, the accuracy of the Possion’s ratio is higher.
