The invention relates to the oil industry and can be used for simultaneously producing electric power and oil using by-products of a multipurpose power plant. The aim of said invention is to increase the oil recovery by the actively stimulating formation. The inventive method makes it possible to use all actually known agents, i.e. carbonic acid gas, steam and oxygen. The inventive methods for increasing the oil recovery of a formation consist in pumping the by-product of the multipurpose power plant into an oil reservoir, wherein said multipurpose power plant is provided with a piston engine which uses natural gas and comprises a membrane reactor, the ceramic ion-transport membranes of which are made of metal oxides. Steam, oxygen and carbonic-acid gas are the by-products of the multipurpose power plant, wherein by adjusting the volume ratios of pumped COand formation oil and pump-in pressure a technogenic retrograde liquid-gas system is set up, said system makes it possible to increase the oil recovery of the productive formation by dissolving the oil in carbonic acid gas. |
