摘要
This paper presents a new method for amplitude versus offset (AVO) nonlinear inversion that solved by support vector machine(SVM). First the main principle of SVM is described,then the SVM model are established for AVO inversion. Finally, both real data and synthetic model are inverted based on SVM,the results show that the proposed method can resolve limitations associated with conventional inversion methods without sacrificing inversion effects. It can extract elastic parameters from synthetic seismogram directly. Meanwhile the method is characterized by high inversion velocity and good stability.
