The polymer oil displacement agent which is suitable for high-temperature and high-salt formation in Zhongyuan Oilfield is synthesized with the monomer of AMPS/AM. Evaluation results show that the polymer has good temperature tolerance and salt resistance performance. At the temperature of 110℃ and total salinity of 220000mg/L, in which the total amount of Ca2+ and Mg2+ is 5000mg/L, the polymer can maintain good chemical stability. By thermal stability testing for 90 days, the solution viscosity of 3000mg/L polymer can reach a level of 9.2mPa.s.
