FIELD: oil and gas production.
SUBSTANCE: invention is related to oil production industry, namely, to methods for displacement of oil due to reduction of permeability in water-conduit channels of bed and better coverage of bed by waterflooding. Method for displacement of oil by waterflooding includes injection of water solution of reagent RITIN-10 and xanthan biopolymer with their ratio of 1:0.5-2.
EFFECT: improved efficiency of oil displacement due to better rheological properties of composition in mineralised water.
