FIELD: oil and gas production.
SUBSTANCE: method to stabilise an aqueous solution of polyacrylamide consists in preparation of polyacrylamide in water with concentration from 0.15 to 0.30 wt %. Then polyacrylamide is dispersed by mixing of the produced solution with angular speed from 14000 rpm to 17000 rpm.
EFFECT: method makes it possible to reduce energy intensity and time for solution preparation, to preserve rheological properties of a solution within a long period of time, to increase efficiency of using the produced solution due to stabilisation of its dynamic viscosity.
