Metodo para determinar el grado de degradacion de soluciones polimericas mediante un modelo reologico

A method for determining the degree of degradation of a polymer solution comprising a polymer dissolved in water with a certain salinity and used in an enhanced oil recovery (EOR) process, said method comprising the following steps:

• a) determining the critical deformation rate scr and the dimensionless parameter Υ, which is a critical value related to the transit time of the solution particles through regions where deformation rates could cause degradation, in order to determine the degree of degradation of the polymer solution based on these two critical parameters;
• and
• b) comparing the effective local deformation rates occurring in the flow within a given flow fitting with the critical deformation rate scr and the parameter Υ, in order to determine whether degradation occurs in any region of the flow in a computational fluid dynamics simulation.
