To study the complex flow characteristics of polymer solution in reservoir porosity,experiments were carried out for the flow of partially hydrolyzed polyacrylamide(HPAM) solution in tubes of 10～350μm in diameter.The results show that under the experimental conditions specified in this paper,the flow laws of HAPM solution significantly deviate from those of non-Newtonian fluid mechanics in conventional scales.When the diameter of tubes is small,its average cross-section flow velocity is higher than the conventional result.The smaller the tube diameter,the greater the deviation will be.
