FIELD: mining.
SUBSTANCE: here is disclosed method of water production insulating in watered oil reservoirs; said method consists in preparing processing reagent out of polyacrylamide, chromium acetate and water and in pumping it into reservoir; during preparation of processing reagent dry mixture is preliminary made containing, wt %: polyacrylamide 60-75; "РИТИН-10" 5-15; chromium acetate 5-10; bentonite clay 10-15; glycerin 0.3-1.0; said reagent pumping is performed in form of suspension of produced dry mixture in water with concentration 0.2-0.7 wt %.
EFFECT: increased processibility of preparing composition to pumping in field conditions, simplification of process, reduction of labour intensiveness and increased accuracy of components dosing in mixture; eased transporting and storage of reagent on site.
