Synthesis and Performance Evaluation of Temperature Sensitive Oil Displacement Agents
Acrylamide,N,N-dimethylacrylamide and cetyldimethylallylammonium chloride were used as synthetic monomers,and the temperature-sensitive oil displacement agent was synthesized by hydrolysis process after copolymerization.It was seen from the infrared spectrum curve that the polymerized monomers of the temperature-sensitive oil displacement agent were all connected to the molecular chain of the nano-drag reducer.The synthesized polymer had excellent tackifying,salt resistance,shear resistance,and temperature-sensitive properties.In a certain range,the viscosity increased with the increase of temperature.
