FIELD: oil and gas extractive industry, in particular, methods for increasing oil recovery of oil wells.
SUBSTANCE: method includes drilling force and product wells, forcing into deposit through force wells under excessive pressure of displacing agent in form of water, thickened with water-soluble polymer composition. For that purpose in place where it is forced into formation, water solution of high-polymeric composition is forced through a system of spinnerets, consisting of at least two blocks, with linear speed of 50-150 m/s. Spinneret blocks are made with decreasing cross-section of actual spinnerets, which in each block are shifted in transverse direction so as not to form through axial filtration channels.
EFFECT: increased efficiency of method.
