: According to the seepage theory of polymer solution in porous media and the node system analysis method, the dynamic equation of polymer flooding well is deduced. The relationship between sucker rod and oil pipe, plunger and bushing, sucker rod and liquid column , The tubing and liquid column, and the solution of the friction force when the fluid passes the swimming valve. The relationship between the maximum load, the minimum load, the minimum tensile strength, the use coefficient and the displacement coefficient are established. The polymer Driven rod pump oil outflow curve calculation method.Using the node analysis software, the production data of 13 polymer flooding pumping wells in the field were dynamically fitted. The results showed that the average error of fitting stroke was 9.37% Relative error of 3.08% .To this end, we should use long stroke, slow stroke, large pump diameter and other pumping parameters to improve the combination of well production
