Polymer flooding is a tertiary oil recovery technique for EOR after water flooding，which has been applied in different types of oil reservoirs achieving good results. The polymer flooding effect would be affected a lot due to plane heterogeneity in the development. Three kinds of heterogeneous models including permeability，thickness and geometry form were proposed based on the distribution characteristics of the sedimentary micro-facie of certain reservoir. Three types of theoretical reservoir simulation models were built by applying the method of reservoir numerical simulation. The polymer flooding effect of different injection-production patterns was studied under the production conditions of each model. The research result shows that cumulative oil production and initial daily oil production were different at distinct injection-production pattern at the same working system. For the thickness heterogeneity reservoir，the reservoir with injector located in thicker layer and producer located in thinner layer has a better development effect than the contrary pattern. For the permeability heterogeneity reservoir，the reservoir with injector located in higher permeability and producer located in lower permeability has a better development effect than the contrary pattern. For the geometry form heterogeneity reservoir，the reservoir with injector located in narrow zone and producer located in wide zone has a better development effect than the contrary pattern.Injection-production pattern should be optimized to improve development effect of the polymer flooding.
