▎ 摘　　要

NOVELTY - A modified graphene oxide comprises amphiphilic polymer and graphene oxide prepared via chemical grafting. USE - Modified graphene oxide used for preparing viscosity reducing oil displacement agent (claimed). ADVANTAGE - The product has good amphiphilic performance, has lower surface tension, reduces the interface tension between water/kerosene emulsification effect, and has average oil displacement rate of 10%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of modified graphene oxide comprising obtaining 50-100 nm graphene oxide, mixing with amphiphilic polymer, adding carboxyl activator, and reacting.
