FIELD: oil production industry.
SUBSTANCE: method involves successively injecting aqueous solution of polymer - polyacrylamide and aqueous alkaline agent solution through injection well. The polyacrylamide solution is injected in liquid waste hydrocarbon which is obtained during isoprene production by two-stage dehydration thereof after isoprene separation and cleaning. The alkaline agent is composition consisting of aqueous liquid glass solutions and caustic soda.
EFFECT: increased efficiency of oil reservoir development and intake capacity of injection well during injection operation performance.
