Real hydrocarbon trap is formed by reservoir (fluid saturated porous medium), compact overlying and underlying formations (ideal elastic media). In this paper, a mixed finite difference method is given, which uses acoustic wave equation to describe wave behavior in an elastic medium, and adopts Biot's P wave equation to depict wave behavior in fluid saturated porous medium. Numerical value modeling result says that this method not only depicts exactly the wave behavior in real hydrocarbon trap but also takes less internal storage and time of computer.
