低渗透油田由于储层物性差、非均质性强，进入中高含水开发期后，油藏水驱状况变差、水驱油效率降低，含水上升速度加快，油藏稳产形势严峻，常规手段控水稳油及提高栗收率难度加大。因此，本文通过借鉴东部油田成功案例，结合低渗透油藏储层特征及室内实验基础上，应用聚合物纳米微球在油层中深部封堵和驱油的双重特性，开展先导性矿场试验，注入后试验井组水驱状况变好，试验井组提高采收率效果明显，有效丰富了低渗透油藏提高采收率稳产技术体系．为低渗透油藏提高采收率奠定了基础。

Low permeability oil fields due to poor reservoir properties, the strong heterogeneity, access to high water cut stage, reservoir water flooding situation worse, the water flooding efficiency, cut rising faster, the reservoirs stable situation is grim, conventional means of controlwater-stable oil and enhanced oil recovery more difficult.Therefore, by drawing on the eastern oilfields success stories, combined with low permeability reservoir characteristics and laboratory experiments on the basis of the application of polymer nanospheres in the deep reservoir block and drive the dual characteristics of the oil, to carry out a pilot test,group of test wells after injection water flooding situation changed for the better group of test wells to improve recovery effect is obvious, and effective rich it low permeability reservoirs to improve recovery stable system, laid the foundation for low permeability reservoirs to enhance oil recoverv.
