Zusammenfassung:FIELD: oil production industry, particularly enhanced recovery methods for obtaining hydrocarbons. ^ SUBSTANCE: method involves producing oil through producing wells and injecting working agent through injection wells in cyclic regime along with arithmetical mean injection well intake capacity determination; referring wells having intake capacity less than average intake capacity value to wells with low injectivity; referring wells having intake capacity greater than average intake capacity value to wells with high injectivity; pairing neighboring well with low injectivity and well with high injectivity; hydraulically communicating all injection wells through land-based water line system to provide working agent flow from well with low injectivity to well with high injectivity. As working agent is injected in cyclic regime paired wells with high injectivity and low injectivity are simultaneously shut-down and brought into operation. Injection cycle includes injection operation to be carried out for 10-20 days and well shutdown for 10-20 days. ^ EFFECT: provision of injection well cooperation after working agent injection termination and injection well bottom cleaning by outflow. ^ 1 ex
