FIELD: oil and gas production.
SUBSTANCE: invention, in particular, relates to producing and injecting wells operated in uniformly stratified and fractured reservoirs. Formulation according to invention containing water-soluble polymer (0.05-0.5%), alkali (1.0-5.0%), and water is characterized by additionally containing acetone-formaldehyde resin (2.0-90.0%), utilizing polyacrylamide or polyethyleneoxide as polymer and sodium hydroxide, potassium hydroxide, or soda ash as alkali.
EFFECT: improved strength characteristics of formulation, which represents homogenous elastic system deeply penetrating into high-permeable formation, more fully mudding pore channels and redistributing water to low-permeability non-watered zones, reduced gel formation range of formulation, and expanded possibilities thereof.
