Abstract On the base of polyacrylamide with high molecular weight,the water-soluble PAM microgels was prepared.The crosslinked structure of the microgels is composed of σ bands,which makes little changes of the viscosity in the conditions of high temperature and salinity.At 45℃,the recovery of 15‰ microgels obtained 25% in brines.The PAM microgels is found to have special property in EOR by the research on it.
