Flooding in the polymer solution into the process, will experience the injection pumps, injection pipes and equipment, borehole, near wellbore and formation of shear degradation of porous media, leading to the solution viscosity significantly down. As the struc tural peculiarities of polymer in the shear branch has significant outstanding performance,also in the displacement has a broad application space, the study of polymer shear resistance branches has practical significance In this paper, the shear character experiment of HPAM and dendritic polymer has been conducted, using Wuyin stirrer and perforating hole method. The paper studies the rheological behavior of the polymer before and after cutting. The result shows that the viscosity of polymer solution increases as the concentration increases. The viscosity decreases rapidly as the shear rate increases under high shear rate, which demonstrates that the polymer has good shear property. Also, the dendritic polymer solution maintains high viscosity under low shear rate, which could improve the coefficient of fluidity. The result also manifests that the dendritic polymer shows superiority to HPAM in respect of shear resistance. We also use the onedimensional model of fill sand, respectively established residual resistance factor and resistance factor without perforations cut and after cut of dendritic polymers and HPAM ,resulte shows： dendritic polymers before and after cut,there is little difference between the residual resistance coefficient, indicating that the dendritic polymers has excellent shear properties.
