FIELD: oil and gas production.
SUBSTANCE: procedure consists in pumping fringe of water solution of polymer into pressure wells According to the invention concentration of polymer is chosen from a condition of transition of filtration flow of polymer solution in a pay in a mode of elastic turbulence at maintaining the condition in accordance with an analytic expression.
EFFECT: raised recovery of oil due to extraction of capillary replaced oil from collector
