Abstract The induced polarization sounding curve inversion is based on the resistivity inversion, using the equivalent resistivity. There are three methods for induced polarization inversion, i.e., linear inversion, formalism inversion and non-linear inversion. Through calculation and analysis by means of programming the horizontally layered model, the authors made a comparative study of the time-consuming conditions and effects of these three inversion methods. It is considered that the non-linear inversion method is the best inversion method in theory, whereas the linear inversion method can be satisfactorily used in actual production.
