英文摘要	The magnetic gel microspheres P(AA-AM-AN)/Fe3O4 were prepared by inverse emulsion polymerization and precipitation polymerization using iron oxide (Fe3O4), acrylamide (AM), acrylic acid (AA) and acrylonitrile (AN) as raw materials. The P(AA-AM-AN)/Fe3O4 were characterized by scanning electron microscopy(SEM), Fourier transform infrared spectroscopy(FTIR) and vibrating sample magnetometer(VSM). At the same time, The water-absorption performance of the magnetic profile control agents were studied under different preparation conditions and the profile control performance was discussed under simulated stratum environment condition. The experimental results show that the P(AA-AM-AN)/Fe3O4 magnetic composite microspheres were prepared, the microspheres have superparamagnetism, and can realize magnetic separation and recovery. The prepared microspheres have good transport properties due to the presence of hydrophobic polyacrylonitrile. The water-absorption performance of the magnetic gel microspheres is superior to others when the mass ratio of AN and P(AA-AM)/Fe3O4 is 1.25: 1, or rather, the water absorption rate is as high as 82.8 g/g. Besides, the water absorption rate of the magnetic gel microspheres was gradually increased with the increase of the water temperature of reservoir formation, and the decrease of NaCl content. © 2018, Higher Education Press.
