| Abstract: | During the seepage flow of polymer solution, when seepage flow rate surpass the critical rate, the rheological property changes from shear thinning type to shear thickening type, that is it shows double power law exponent characteristics (viscoelasticity). Formula of multi dimention(radial flow and 2D elliptical flow etc.) fix constant seepage flow pressure change is given out and high pressure difference caused by large injection is discussed according to the rheological property of this non Newton double power law exponent fluid. |
