Resumo |
Herein, we report a novel acrylamide copolymer with antimicrobial property as an enhanced oil recovery chemical. The copolymer was synthesized from acrylamide (AM), acrylic acid (AA) and 2-((2-(acryloyloxy)ethyl)dimethylammonio)ethyl sulfite (ADMES) using oxidation-reduction initiation system. Subsequently, the copolymer AM/AA/ADMES was evaluated and characterized on several aspects such as IR, <sup>1</sup>H NMR, intrinsic viscosity, and dissolubility. The AM/AA/ADMES solution exerted remarkable thickening ability, salt tolerance ability and viscoelasticity. In addition, the rheological properties, temperature resistance ability and long-term stability of AM/AA/ADMES were investigated systematically in the presence of sulfate-reducing bacteria and relatively low viscosity loss could be obtained compared to partially hydrolyzed polyacrylamide. On the basis of core flooding experiments, AM/AA/ADMES was found to be a valuable prospect with 10.5 resistance factor, 4.6 residual resistance factor and up to 11.0% enhanced oil recovery. |
