FIELD: oil industry.
SUBSTANCE: invention relates to development of oil fields, and specifically to methods of leveling of injection which open differently permeable bed intervals. Assigned task is solved by the fact that the offered method of leveling of profile of water injection well, which includes successive pumping of fringe of SPC - stitched polymer composition based on copolymers of acrylamide and acrylic acid with the stitcher - salt of trivalent chromium with addition of CS - cationic surfactants, distinguished by that CS solution fringe is pumped after SPC fringe, in which CS is added. Acid fringe or solvent fringe and acid fringe is pumped additionally between SPC fringe, in which CS is added, and CS solution fringe.
EFFECT: technical result consists in improvement of efficiency of the method of leveling of profile of water injection well due to increase of isolation of highly permeable intervals and redistribution of water injection to low-permeable intervals.
