Artificial neural network is one of study fruits in artificial intelligence field which is being developed very quickly at present time. Based on introducing the theory of BP network, this paper has put forward a impedance inversion method using BP network model to solve some problems such as the initial model sensitivity, frequent local traps for the conventional impedance inversion based on model. The result of real data indicates the method is effective and getting the satisfying high precision inversion results.
