FIELD: petroleum production.
SUBSTANCE: invention relates to the petroleum industry and can be used in development of petroleum deposits by the flooding method with a formation temperature of 20 to 95°C, with a total salt content in the formation and injected water from 0.034 to 24.0 wt.%. In the method for production of petroleum, consecutively injected into the formation are an aqueous solution of an acrylamide-based polymer with a surface-active composition containing 0.001 to 0.15 wt.% anionic surface-active agent (recalculated by 100%) at a weight ratio of the anionic surface-active agent to said polymer of 0.009÷2.7, an aqueous solution of an acrylamide-based polymer, and/or water continuously or cyclically.
EFFECT: an increase in the petroleum recovery coefficient and intensification of production of petroleum.
