FIELD: mining. ^ SUBSTANCE: control method of water flooding of non-homogeneous reservoir beds of deposits of minefields by means of cross-linked polymer systems with filler involves pumping of mixture in cycles with hold intervals in number of up to 12 cycles; at that, first, polyacrylimide with stitcher is pumped in portions in each cycle. Chrome acetate is used as stitcher, and then filler is pumped, and 0.7% (by weight) solution of calcium carbonate is used as filler; quantity of calcium carbonate is increased in each next cycle by 0.01 wt %. ^ EFFECT: reducing the number of by-effects of use of cross-linked polymer systems, uniform distribution of mixture, owing to which water flooding of the well remains controllable and reversible; elimination of blockage of well channels; simplification of cleaning of sludges from the well. ^ 1 ex |
