Abstract
The three-component polyurethane composition is developed to create impervious screens in rock mass by hydraulic fracturing technique. Formulas for working fluids and their injection charts are given. The article describes a lab test and the test data on polymer setting time versus activator concentration and on effect of the fluid composition on the permeability of a porous medium at the limited flow rate of reagent per unit area of the screen.
