Abstract

The elastic wave impedance inversion is a “bright point” in the seismic inversion technique in recent years, and alsoa “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/gasbearing 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.
