With the rapid development of the national economy, in order to meet the huge demand for oil products, people have carried out the positive exploration for the tertiary oil recovery technology. As an effective EOR method, polymer solution flooding is widely used and has rapid development. In this article, a micro-pore viscoelastic fluid flow model was established; The upper-convected Maxwell constitutive model and the finite element fluid dynamics software POLYFLOW were used to solve the model; the velocity contour maps and stream function of the model were obtained; the influence of the relaxation time, flow and entrance width of the microscopic sweep efficiency was analyzed.
