Beschreibung
Zusammenfassung:	FIELD: enhanced recovery methods for obtaining hydrocarbons, particularly with the use of heat. ^ SUBSTANCE: method involves delivering oil gas to bottomhole formation zone to provide gaslift oil production. Bottomhole formation zone is previously heated by supplying heated degassed oil in well. Viscosity is reduced in produced oil. Then oil gas is separated from produced oil in separation unit and necessary oil gas quantity is accumulated. Oil gas is delivered into bottomhole formation zone through separation unit in compressed and heated state, wherein oil gas is compressed and heated by means of steam ejector in liquid mixture. ^ EFFECT: increased efficiency due to improved conditions of oil filtration from reservoir into well. ^ 1 x, 1 tbl, 1 dwg
