Preparation of hydrophobically-modified acrylamide copolymers using poly(ethylene imine) as a photoinitiator and its performance evaluation in Bohai oilfield



This paper presents copolymers of acrylamide, N,N-dimethyl-N-vinylnonadecan-1-ammonium chloride and N-(2,4-dimethylpentan-2-yl) acrylamide synthesized by photopolymerization using modified poly(ethylene imine) as initiator in water. These hydrophobically modified acrylamide copolymers were dissolved in the brine that was used in enhanced oil recovery in Bohai oilfield. It was found that when the content of N-(2,4-dimethylpentan-2-yl) acrylamide and N,N-dimethyl-N-vinylnonadecan-1-ammonium chloride were 0.1 mol % and 0.3 mol %, respectively, the resulting polymer could meet the demand of solution time and the polymer mechanical shear stability required in Bohai oilfield. The solution properties of synthesized copolymers were compared with the hydrophobically modified polymer currently used in enhanced oil recovery in Bohai oilfield.
