Viscosity-concentration and temperature performance are the prerequisite constraint factor of the application of
polymer flooding in the oilfield. The static and dynamic adsorption of the polymer in the core can affect the performance
of polymer flooding. Based on the viscosity-concentration, temperature and the static, dynamic adsorption results of six
kinds of polymers, DQ3500 is chosen as the most suitable polymer for Zahra oilfield. Its affects show that oil recovery is
increased by 7% and water cut is reduced by 20%.
