▎ 摘　　要

NOVELTY - Acrylamide derivative based polymer (I) is new. USE - Acrylamide derivative based polymer. ADVANTAGE - The acrylamide derivative based polymer has high temperature and salt resistance, maintains a high viscosity under high temperature and high salt conditions, and has good shear resistance and cut performance. DETAILED DESCRIPTION - Acrylamide derivative based polymer (I) is new. m and n=number of each structural unit, non-zero natural numbers, where ratio of m to n is 1:1-1:2.5; R=graphene oxide group; and X=Na and K. .. An INDEPENDENT CLAIM is included for an oil-displacing agent, which comprises polymer.
