EMULSIFIER FOR INVERT EMULSION TO INCREASE OIL RECOVERY OF FORMATIONS Russian patent published in 2020 - IPC B01F17/16 B01F17/22 C09K8/68

Abstract RU 2720113 C1

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention relates to oil industry, in particular to emulsifiers of invert emulsions for increasing oil recovery of formations. Emulsifier of invert emulsion for increasing oil recovery of formations, including oil-soluble surfactant - surfactant Neonol AF₉-6, oleic acid and hydrocarbon solvent, additionally contains cocamidopropyl dimethylamine or oleylamidopropyldimethylamine, and as a hydrocarbon solvent - furnace or diesel fuel, with the following ratio of components, wt. %: Neonol AF₉-6 5–10, oleic acid 5–15, cocamidopropyl dimethylamine or oleylamidopropyldimethylamine 5–15, furnace or diesel fuel, the weight ratio of oleic acid and cocamidopropyl dimethylamine or oleylamidopropyldimethylamine ranges from 1:1.5 to 1.5:1.

EFFECT: technical result is increase in the emulsifier action efficiency due to increase of displacing ability in relation to oil.
