摘　　要：构造指数是欧拉反演中最重要的参数,以往选取构造指数往往根据地质先验信息和人工经验试探选取,这样往往不能快速、准确地确定反演构造指数,从而影响反演效果,甚至反演失败.本文提出利用异常值自动估算构造指数,这样避免了经验选取构造指数产生的不确定因素的干扰,可以快速方便地选出较合理的构造指数,提高反演效率.模型实验显示了该方法良好的反演效果,证明了文中提出的方法的可行性.Structure index （SI） is the most important parameter in Euler deconvolution. If we want to acquire favorable deconvolution solution, only to choose the accurate SI. Formerly, SI is selected by the geological information, artificial experience and prior experience of test selection, which is often not quickly and accurately to determine the best SI. Whereas, a new method to resolve this problem is brought forward in this paper, that is, using the value of abnormity to compute the optimal SI automatically, so to avoid the interference of uncertain factors caused by artificial experience, and quickly and easily determine a more reasonable SI. Thereby, this method improves the efficiency of Euler deconvolution. Model experiments showed the good results by using the SI determined by statistical principle of decovolution model, and testified the validity of the new method, which is brought forward in this paper.
