非均质储层中聚合物流度控制对驱油效果影响
Study on Mobility Control of Polymer Flooding in Heterogeneous Reservoir
摘要
Abstract
In order to further study the effect of mobility control on low permeability layers of heterogeneous reservoir ,a numerical simulation model for polymer flooding is established which based on the data of indoor core simulation experiment . This model is used for simulating heterogeneous reservoir with 1 000 × 10-3 μm2 ,300 × 10-3 μm2 and 50 × 10-3 μm2 of the effective permeability respectively .Three kinds of polymer solutions which have different concentrations are injected into core , by changing the way of injection to achieve mobility control .The effect of polymer slug size and sequence on oil displacement is analyzed .The results show that under the same conditions of polymer solution number ,slugs‐injection schemes achieve better effect with polymer concentration ratio of 2∶3∶4 .The effect of slugs size on high permeability layers is little ,while the effect on low permeability layers is obvious .So it can be indicated that measure of mobility control is an effective action to enhance oil recovery .关键词
