The effects of temperature and heterogeneous fluids distribution related to capillary pressures on seismic signatures are of crucial importance for interpretation of seismic field data. We present a method to numerically simulate the temperature-dependent velocities of seismic P-wave in rocks saturated with multi-phase fluid. Both spatial variation of fluid saturations related to the capillary effects and the influence of temperature on the seismic velocities associated with the chemo-mechanical weakening effects of fluids are taken into account. The numerical results indicate that velocities of P-wave show significant dependence on saturations of multi-phase fluid mixtures and temperature-related effects, and exhibit some interesting characteristics.
