The aim of this paper Is to discuss how use the simulated annealing (SA) method in seismic inversion, and form the fast simulated annealing (FSA) technique by using a fast cooling schedule. It is the most advantage that SA method can obtain the globally optimum solution by a simulated annealing process. SA algorithm is applicable to nonconvex optimizationproblem of seismic inversion. In order to improve the computational speed of classical simulated annealing (CSA), FSA method is used. Because the convergent speed of FSA is faster than CSA, FSA can save the computational time. This method advance the applicability of simulated annealing to real seismic data processing. The example of synthetic and real data show that the accuracy of the method is satisfactory.
