In order to do research on pipe flow and pump characteristics of polymer flooding and water flooding rod-pumped well in especially high water-cut stage, rheometric test aimed at production stream from polymer flooding and water flooding rod-pumped well in especially high water-cut stage has been made, and the characteristic of production stream in especially high water-cut stage is confirmed as Newtonian fluid. Experiments using different mediums about pipe flow and pump characteristics is made. Frictional resistance and coefficient of friction resistance of annulus fluid between sucker rod and the pipe flow is calculated under different working conditions. Frictional resistance between plunger and pump barrel under different parameters is calculated based on related theory of pump characteristic and the strained analytical model of oil-well pump. Besides, using the theory of slit flow and hydraulic -clamping pressure, the frictional resistance is calculated, and the error between the result and measured value is no more than 13%.
