Aim to the problem of high water-cut rate in Bohai oilfield, a new organic polymer recycling agent was used to enhance oil recovery by the flocculation with the residual polymer in the formation. This study used polymer and organic polymer recycling agent composite flooding to research the effect of injection amount, displacement speed, injection opportunity and injection round by physical simulation experiments to optimize injection parameters of composite system, taking residual resistance factor as evaluation indicator. The results showed that the best injection amount was 0.3PV. The medium speed, the better blocking effect. And the earlier injecting organic polymer recycling agent, the more effectiveness acquired. In addition, it was found that adding the injection round could not improve the blocking effect. The major factor was the amount of first injection.
