Abstract: On low frequency and ignoring the EM effect, the finite element method and the Cole-Cole model were used to take numerical simulation for IP response in frequency domain. Under the 3-D condition, the electrical field boundary value problems and the variational problems of were given, the frequency response of Cole-Cole model was introduced into geoelectric model, the finite element method was used for element subdivision, interpolation, integration and general synthesis of the model, and the parameter of IP-f_s (breadth frequencies) represented the polarization strength in frequency domain was obtained by solving the equation. The different response curves of f_s were obtained by changing the parameters of the geoelectric model, and the simulation results were consistent with the real results，indicating the method is correct and applicable.
