Application of elastic wave impedance inversion technique

The elastic wave impedance inversion is a bright point in the seismic inversion technique in recent years, and also a hot point in the inversion research. Elastic wave impedance inversion is a seismic inversion technique which combines conventional acoustic impedance inversion with AVO inversion. It uses different offset gathers data and S-wave、P-wave and density data to carry out joint inversion of elastic parameters related to lithologies and oil/gas-bearing ability, and determine the reservoir properties and oil-bearing ability. The basic principle and method of the pre-stack elastic wave impedance inversion are briefly expounded, and the application case is given.
