The present invention relates to a method for increasing oil recovery from an oil-bearing formation including the following successive stages of treating the formation: injecting an invert emulsion in a volume of 3-5 m3/m of perforated interval thickness followed by squeezing down an acidic composition or a composition containing a nonionic surfactant in a volume of 2-3 m3/m of perforated interval thickness to the formation, injecting a highly stable direct emulsion containing a colloidal solution of silicon dioxide nanoparticles in a volume of 3-7 m3/m of perforated interval thickness followed by squeezing down a liquid from a reservoir pressure maintenance system to the formation.
