【Abstract】 The viscosifying mechanism of magnetized polymer is discussed through the measuremeat ofthe viscosity of polymer solution before and after magnetization. The influence of magnetiza-tion on polymer flooding is analyzed on the basis of core displacement experiments. The regu-larity of the effects of magnetizing type and magnetization on oil recovery of polymer floodingis obtained.更多还原
