| Abstract: | A new CT method of physical parameters for stratiform media including Fermat principal and Radon transform,based on the equivalent model of porous media,is studied,and inversion of physical properties such as velocity,porosity,density and wave impedance is made availing of algorithm.From theoretical analysis and result of inversion,it could be drawn that the method is of practical value and may lead to effective prospecting for oil,simplifying wave propagation equations in dual phase porous media. |
