Viscoelasticity of Polymer Solution Impact on Oil Displacement Effect

摘要

At present, petroleum industry has been large-scale application polymer flooding means to improve oil recovery in China which Daqing Oilfield polymer flooding technology has made certain achievements. The viscoelasticity has influence on polymer solution flooding. Through indoor simulation flooding experiment determinate the effect of viscoelasticity. The experimental results show that the viscoelasticity increased with the relative molecular mass increase and polymer enhanced oil recovery degree increase.
