Abstract

Настоящее изобретение относится к способу добычи текучей среды, содержащей нефть и воду, из нефтеносного пласта и отделения нефтяной фазы и водной фазы от добытой текучей среды. Водная полимерная смесь образуется с помощью смешивания полимера с водой, имеющей общее содержание растворенных твердых веществ от 200 до 15000 ч./млн. Водная полимерная смесь закачивается в нефтеносный пласт, и после закачивания водной полимерной смеси в пласт из нефтеносного пласта добывается текучая среда, содержащая нефтяную фазу и водную полимерсодержащую фазу. Насыщенный солевой раствор смешивают с добытой текучей средой для повышения отделения нефтяной фазы от водной полимерной фазы.
