Beschreibung
Zusammenfassung:	FIELD: oil industry, particularly enhanced recovery methods for obtaining hydrocarbons. ^ SUBSTANCE: method involves cyclically extracting oil from the reservoir zones through productive wells and injecting working agent into reservoir zones through injection wells. Discharge water and oil-field water of low mineralization having thickness of 1-1.005 kg/m3 is used as the working agent. Discharge water is cyclically injected in upper reservoir zones. Oil-field water of low mineralization is cyclically injected in lower reservoir zone for 7-9 months and discharge water is also cyclically injected in lower reservoir zone for 3-5 months. ^ EFFECT: increased output.
