摘　　要：充分利用多种位场数据处理方法之间的互补性,以频率域下延方法为核心,提出一套重力勘探数据下延的优化算法。通过在Matlab7.0平台设计和正演理论模型异常进行仿真试验,结果表明各优化因子都在算法中起到明显优化作用,优化算法能够取得比单一下延方法更好的效果。优化算法的实质是多种位场处理方法合理组合,这给出了一种处理棘手的位场运算问题的思路。Make full use of complementarity of a variety of potential field processing approaches,we proposed the optimization algorithm of downward continuation for gravity field. By designning theoretical model to simulate gravity abnormal ,we test the optimization algorithm on Matlab7.0 platform.The results show that the optimization factors played evident optimize role in the algorithm,and the optimize the algorithm can achieve better processing results more than the single method of downward continuation. Optimization algorithm is essentially a kind of combination of avariety of potential field processing approaches,which gives a new idea to deal with the difficul issue of field computing.
