Abstract

Настоящее изобретение относится к способу добычи нефти. Определяется отношение действующих масс (MAR) двухвалентных катионов к одновалентным катионам воды из нефтеносного пласта, и водная вытесняющая текучая среда, имеющая общее содержание растворенных твердых веществ от 200 до 5000 ч./млн и отношение MAR двухвалентных катионов к одновалентным катионам от 70 до 130% от отношения MAR двухвалентных катионов к одновалентным катионам пластовой воды, вводится в пласт. Нефть добывают из пласта после введения водной вытесняющей текучей среды в пласт.
