摘要

Nano-SiO2 was functionalized to synthesize a hyperbranched polymer for enhanced oil recovery. The hyperbranched structure, formed by introduction of functionalized Nano-SiO2, endowed the hybrid polymer with excellent shear resistance and viscoelasticity. Based on core flooding experiments, the hybrid polymer could establish good flow resistance and effectively improve oil recovery.
