Comparing the ability of global optimized between binary code and real code of genetic algorithm based on the genetic operation, which was the best optional optimization preserving strategy, stochastic uniform selection, scattered crossover, Gaussian mutation and distributed parallel genetic algorithm. Real-coded distributed parallel genetic algorithm was better than simple genetic algorithm. It brought forward global optimized wave impedances inversion founded on parallel genetic algorithm and checked out the effectiveness of parallel genetic algorithm by using numerical model and the practical seismic section. The method of wave impedances inversion can provide an improved train of thought on seismic attribute optimization based on genetic algorithm.
