地震静校正全局最优化问题的求解

A GLOBAL OPTIMIZED ALGORITHM FOR SEISMIC RESIDUAL STATICS CORRECTIONS

A global optimized algorithm is developed in this study for dealing with the problems of nonlinearity and multiparameter characteristics of the residual statics correction method. Integration of the simulated annealing approach with the uniform design optimized method makes the updating of the model more reasonable and therefore,increases the speed of searching for the global optimimzed solution. A procedure is proposed for selecting the temperature parameters of different model components and the process of decreasing the temperature. Here the selection of the temperature parameter is correlated with seismic energy, which makes the algorithm having a self-adapted characteristic. This new algorithm overcomes several shortcomings of the conventional simulated annealing method. Its application to seismic data shows that the algorithm developed in this study is more efficient than the conventional simulated annealing method.
