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.The present invention relates to a method for producing oil. The ratio of active masses (MAR) of divalent cations to monovalent cations of water from an oil reservoir, and an aqueous displacing fluid having a total dissolved solids content of 200 to 5000 ppm and the ratio of MAR divalent cations to monovalent cations from 70 to 130% are determined from the MAR ratio of divalent cations to monovalent cations of formation water, is introduced into the formation. Oil is produced from the formation after the introduction of the aqueous displacement fluid into the formation.
