Способ разработки слоисто-неоднородной нефтяной залежи, включающий закачку рабочего агента в пласты через нагнетательные скважины и отбор нефти из пластов через добывающие скважины, отличающийся тем, что выделяют на залежи пласты с низкой нефтенасыщенностью и проницаемостью и пласты с высокой нефтенасыщенностью и проницаемостью, разработку пластов с низкой нефтенасыщенностью и проницаемостью проводят сеткой скважин в 1,5 - 2,0 раза более плотной, чем пластов с высокой нефтенасыщенностью и проницаемостью, при разработке пластов с низкой нефтенасыщенностью и проницаемостью снижают пластовое давление в зоне отбора на 1 - 5 МПа ниже начального пластового давления, в нагнетательных скважинах в пластах с низкой нефтенасыщенностью и проницаемостью проводят интенсифицирующие работы по увеличению приемистости и периодически закачивают рабочий агент повышенной вязкости с превышением в 1,5 - 2,0 раза объемов закачки рабочих агентов над объемами отбора добываемой продукции до достижения пластового давления на 1,5 - 2,0 МПа выше начального и проявления влияния нагнетательных скважин на добывающие, а отбор добываемой продукции ведут при забойном давлении, соответствующем давлению насыщения.A method of developing a layered heterogeneous oil reservoir, comprising injecting a working agent into the reservoirs through injection wells and extracting oil from the reservoirs through production wells, characterized in that reservoirs with low oil saturation and permeability and reservoirs with high oil saturation and permeability are isolated, reservoir development with low oil saturation and permeability are carried out by a grid of wells 1.5 to 2.0 times denser than reservoirs with high oil saturation and permeability, when developing reservoirs with low oil saturation and permeability reduce reservoir pressure in the production zone by 1 - 5 MPa below the initial reservoir pressure, in injection wells in reservoirs with low oil saturation and permeability conduct intensifying work to increase the injectivity and periodically pump a working agent of increased viscosity with an excess of 1.5 - 2 , 0 times the volumes of injection of working agents over the volumes of production extraction until the reservoir pressure is reached by 1.5 - 2.0 MPa higher than the initial and the manifestation of the influence of injection wells and extracting, and the selection of extracted product was conducted at bottomhole pressure corresponding saturation pressure.
