摘要
为提高石南油田采收率,通过对室内实验数据进行全面分析以及对比,分析了不同因素对聚合物水动力尺寸的影响,建立了不同类型聚合物与岩心渗透率的匹配关系,筛选适合于石南31井区的聚合物配方。通过室内实验评价聚合物驱油体系的性能,确定聚合物驱的最佳段塞大小为0.7 PV。
Through a comprehensive analysis and comparison on indoor experimental data,the author analyzes the influence of different factors on polymer hydrodynamic size and destablishes amatching relation between different types of polymers and core permeability.The best formula for Shinan oilfield polymer flooding was selected.The result of experiment showed the best slug size was 0.7 PV.
