Overview

       The instrument measures the ratio of friction between water and different fracturing fluid and the liquid CO2 at different shear rates at different shear rates and obtain the ratio of the friction of clear water to different fracturing fluid and the friction of liquid CO2 after the thickening of different fracturing fluid at different shear rates.It provides the basis for the evaluation of liquid CO2 frictional resistance after fracturing fluid reducing friction or thickening, further understanding of the frictional resistance variation of liquid CO2 after different fracturing fluids or thickening fluids with different displacement and different well depth and the optimization of fracturing fluid or thickener for thickening liquid CO2 and optimization of fracturing.
