A new method to directly invert the elastic parameters

The aim of seismic data inversion is to assess the physical parameters (including density, elastic parameters and viscous elastic parameters). Defining the best assessing value to be a kind of parameters set, it is simulated that the synthesized seismic records are the most fit to those which were recorded in fields. A new way of directly inversion for elastic parameters has been brought forward in the context. It is suitable to the inversion of elastic parameters in anisotropic media (HTI). It is totally different from those depicted in the previous approaches. In order to classify the strata properties, it utilizes both PP wave and PSV wave to inverse the strata elastic parameters (C11 and C33). It could be called as the inversion of elastic wave equation.
