Fully understanding the reservoir geological features of Block Zhuang1, remaining oil distribution law was summed up by calculating the stress field and water saturation field at the end of the stage on the basis of early water flood-ing numerical simulation, and quantitative analysis was made on reservoir producing and horizontal and vertical remaining oil distribution in the study area. Meanwhile, selective study was carried out on the parameters influencing polymer flooding development effect on the basis of experimental data and oilfield production data. Simulative calculation was conducted on horizon, well pattern, volume ratio, polymer concentration, injection way, injection speed, and etc, and the best assem-blage was selected. Parameters simulation results showed that oil recovery might be enhanced by 6. 89% 10 years later, and water cut might be reduced by 20% at least, increasing oil production and reducing water production remarkably. The results provided theoretical basis for mining plan compiling.
