%X The eccentric wearing of a sucker rod in polymer flooding is much more serious than that in water flooding, mainly due to the normal force of production liquid in polymer flooding. Based on the non-Newtonian fluid mechanics theory, a normal force computational model is established using the upper-convected Maxwell model, and the distribution of the normal force inside the well is confirmed and then put into the mechanical model of the sucker rod. With the real boundary condition, the analysis of the sucker rod is carried out using the finite element method. With Well FU081801 as an example simulation method is validated. The simulation result agree with the detection result, which demonstrates the applicability of this method. Through the method, we can predict the eccentric wearing position of the rods and tubes, as well as the influence of polymer concentration on the eccentric wearing of the sucker rod.
