Popis: By using polymer solution with high viscosity, polymer flooding can enhance oil recovery by reducing the mobility ratio of displacing fluid and oil in formation. Therefore, the core of polymer flooding's ground transportation is to keep the viscosity of polymer solution unchanged. According to the process layout of polymer ground transportation, the experimental device was designed and manufactured to determine viscosity loss of pipelines and elbow. We obtained the viscosity loss variation law of the polymer solutions of different concentrations at different flow velocities when they flow through the pipeline and elbow. The experimental results showed that the viscosity of polymer solution will decrease after the polymer solution flow through pipelines and elbow, due to the shear effect. The higher the velocity, the more significant the viscosity loss.
