The Laboratory Investigation of the Viscosity of EOR Polymers at Various Salinity and Temperature

Several experiments were conducted to verify the effect of salinity and temperature to EOR polymer solutions viscosity. The viscosity of these hydrolysed polyacrylamide solution A, B and C was affected by salinity and testing temperature. The flow behaviour index, n and flow consistency index, k and viscosity of these hydrolysed polyacrylamide solutions were systematically determined over a wide range of temperatures (25 - 90°C) and salinity (5000 – 70000 ppm), using a rotational rheometer Model 1100 Pressurized Viscometer. The outcomes of these measurements suggest that the rheological behaviour of 1000 ppm polymer solution behaves like a non-Newtonian fluid at all the set ranges.
