AI Technical Summary
In the existing technology, single-property heavy oil viscosity reducers or active oil displacement agents cannot meet the needs of high viscosity reservoirs, resulting in poor performance in field applications. Furthermore, compound products have chromatographic separation problems and lack universality.
A modified surfactant monomer was developed and copolymerized with monomers such as maleic anhydride and sodium α-alkenyl sulfonate to prepare a single-component viscosity-reducing and high-activity oil displacement agent, FVR-01, for use in water-driven cold recovery of heavy oil.
It achieves a viscosity reduction rate of 99.9% in high-viscosity reservoirs while maintaining interfacial activity, avoiding chromatographic separation, and improving oil displacement and recovery.
