Study on Rheological Properties of the Activated Polymer Flooding System

Abstract:

A novel kind of activated polymer flooding (APF) composing activated agent and polymer components designed for the target reservoir is studied for the first time. Interactions between the activated agent and natural surfactant from heavy oil, and the synergistic effect between the activated agent and polymer are existed. APF could enhance more oil recovery with less investment, compare to polymer-surfactant flooding (PSF) in the offshore heavy oilfield. The optimum formulation of APF is 1200mg/L polymer + 500mg/L activated agent. Experimental results implies that (1) the contained amide groups and sulfonic groups in APF can form hydrogen bonds with-NH₂ groups contained in PM, (2) the apparent viscosity of APF was higher than PM along with the increase of shear rate, (3) the viscoelasticity, deformation capability and solubility of APF were much better than PM.
