CHEMICAL FOR OIL DEPOSIT DEVELOPMENT AND METHOD OF OIL DEPOSIT DEVELOPMENT USING THIS CHEMICAL Russian patent published in 2015 - IPC C09K8/584 E21B43/22

Abstract RU 2559976 C2

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil industry. Chemical for oil deposit development containing surface active substance (SAS), soap is used as SAS, it is produced by alkali (caustic soda or potassium hydroxide) mixing with vegetable oil, and additionally ultrafine carbon is used as viscosity stabiliser with particles size 10-50 nm, it is produced from vegetation origin substances. Method of the oil deposit development using the above chemical containing injection via the injection wells of the specified chemical in form of 0.5-1% water solution, displacement of reservoir oil by the high-viscosity fluccan force through to the reservoir by the water injected in the injection wells, and further oil recovery via the production wells. Invention is developed in subclaim.

EFFECT: increased oil recovery factor.
