<p>The invention relates to the oil and gas production industry, in particular to a composition for regulating the permeability of an inhomogeneous oil formation, which makes it possible to increase the oil recovery and to intensify the oil production. The problem of the proposed invention consists in producing an effective composition for regulating the permeability of an inhomogeneous oil formation by virtue of reducing the permeability of the highly permeable areas of a water-saturated reservoir. The set problem is solved in that a composition for regulating the permeability of an inhomogeneous oil formation in the form of an aqueous suspension of metal salts, said composition comprising calcium carbonate, calcium hydroxide, magnesium hydroxide, calcium sulphate, sodium chloride, sodium hydroxide, admixtures and water, is characterized in that the composition additionally comprises calcium chloride ???l2, sodium sulphate Na2SO4, silicon dioxide SiO2, calcium oxide ???, sodium carbonate Na2CO3, sodium bicarbonate NaHCO3 and magnesium carbonate.</p> |
