FIELD: oil production. SUBSTANCE: when flooding biologically active substrate of biochemical plant producing protein/vitamin concentrates with additions in the form of polyacrylamide and water with the following ratio (% by weight): 0.01 - 0.3 biologically active substrate of the biochemical plant producing protein/vitamin concentrates, 0.002 - 0.02 polyacrylamide; the balance being the water. EFFECT: increased flooding are of the oil formation, improved filtering capacity of the pumping in agent. 1 tbl
