FIELD: gas and oil production.
SUBSTANCE: according to procedure for control over water flood of non-uniform reservoir consisting in successive pumping polymer in water and solution of aluminium salt with buffer of water between them into reservoir, volume of pumped polymer in water used in form of suspension and solution of aluminium salt is broken into equal portions not less, than two and of 3-50 m3 volume. The portions are pumped successively in cycles with pumping a buffer of water between them amounting to 10-100% volume of portion of each.
EFFECT: raised efficiency of procedure due to more complete mixing of suspension and solution, reduced power and material expenditures.
