摘要: A method of improving the oil-productivity and recovery a layered oil reservoir (1) having an upper layer (2) that is more permeable than lower (3) (1), wherein: - viscosified aqueous liquid injected through injection well (5) into non-aqueous fluid miscible with (3), recovered from formation production (10), viscosity so selected pressure gradient in section larger or equal to confine no-aqueous the enhances cross flow allow limited (2), at least one wells (5,10) comprises transfer substantially horizontal orientation.
