Аннотация
The influence of the solution ionic strength (up to 1.89 M), temperature (up to 413 K) and acidity (pH down to 1.65) on the drag reduction DR and flow rate increment ΔQ of an aqueous solution of the terpolymer containing 71.6 mol % acrylamide, 10.5 mol % acrylonitrile, and 17.9 mol % sodium 2-acrylamido-2-methylpropanesulfonate was studied by capillary turbulent viscometry. The intrinsic performance and the optimum concentrations of the terpolymer under these conditions were determined. The temperature dependence of the flow rate increment for the terpolymer solution passes through a maximum. The turbulence drag reduction for water flows at temperatures exceeding 373 K was demonstrated.
