METHOD OF PROTECTION OF INTERNAL SURFACE OF THE RESERVOIR BOTTOM AGAINST CORROSION Russian patent published in 1994 - IPC

Abstract SU 1433079 A1

FIELD: oil industry. SUBSTANCE: solution of corrosion inhibitor is introduced in the hydrocarbon fluid. The obtained mixture is dispersed in water involving formation of water-in-oil emulsion, density of which is more than that of water phase in reservoir. The emulsion is then applied on the bottom of the reservoir in form of free layer. EFFECT: enhanced efficiency of protection of metal against corrosion. 2 cl, 1 tbl
