The method of oil-water interfacial layers strength evaluation based on rheological researches of model interfacial layers formed by asphaltenes aggregates is tendered. Optimum parameters of model system formation were fitted (concentration of asphaltenes in a solution and time of adsorption layer formation). As a result of rheological parameters of interfacial adsorption oil-water layers studies in the presence of composite surfactants with application of the elaborated method, it is fitted that due to the synergistic effect of components strength properties of formed adsorption layers are reduced. It leads to an increase in the demulsifying effect of composite surfactants.
