Has been proposed identification model for process of the oil-water-gas displacement systems from reservoirs where influence entrance is assumed pressure decreased and output response is coefficient of displacement and argument of the model adopted part of pore volume injected water or aqueous composition of surfactants. Proposed identification model in certain reservoir conditions and certain ratios of invariable coefficients can qualitatively describe all particular processes of the displacement oilwatergas systems from reservoirs. Comparison of calculation quantities with experimental data showed sufficiently good convergence, which enables to consider proposed model adequate to studied process and the estimation method for parameter definition correct.
