摘要(Abstract)：

针对大庆油田二类油层聚驱过程中出现的同层段平面上聚驱和水驱共存的开发格局进行聚水同驱可行性研究。通过数值模拟和物理模拟手段研究不同注入方式、不同接触关系、不同注入速度比等因素对聚水驱接触带开发效果的影响。采用萨北开发区北二西块二类油层聚水同驱单元建立实际模型,结果表明聚水同驱为最佳开发方式,在保证压力平衡的前提下聚水同驱不会影响聚驱效果,利用水驱井还可完善部分聚驱井点注采关系,改善区块的整体开发效果。
Study on the feasibility of simultaneous waterflooding and polymer flooding is based on the current situation of co-existence of waterflooding and polymer flooding on the surface of the same interval during polymer flooding process in under-productive oil layers of Daqing Oilfield.Through numerical simulation and physical simulation,the influences of injection manner,different contact relations and different injection velocity ration on the development effect of the contact zones of polymer flooding and waterflooding.Taking the under-productive layers in western B-2 Block in Sabei area as a practical model for simultaneous waterflooding and polymer flooding,results indicate that simultaneous flooding is the best way for development,which would not affect the polymer flooding effect if pressures remain balancing,and furthermore,the water injection wells could also be adopted for improving injection and production relations of some polymer injection wells in order to promote the general development effect of the whole area.
