Abstrakt:	Presented are the results of laboratory studies on the effect of electrolytes on physicochemical properties of the oil-displacing acid systems based on surfactants, coordinating solvents and complex compounds. It has been found that addition of AlCl3, FeCl3, FeCl2 and MgCl2 electrolytes decreases pH values and increases density and viscosity of the solutions. It enables to control in a wide range physicochemical properties of the systems and their effect on reservoir permeability. [ABSTRACT FROM AUTHOR]
