摘　　要：注聚末期如何突破现有的技术和工艺,提高聚合物的利用率,改善聚合物驱开发效果,是聚合物驱油田开发亟待解决的瓶颈问题。预交联颗粒调剖剂具有较好的体膨性能,调剖粒径、强度和膨胀倍数等可调,可有效地调整吸入剖面,改善聚合物驱开发效果,提高聚合物驱最终采收率。研究了注聚末期颗粒调剖技术的特点及选井选层方法,详细分析了萨北开发区注聚末期颗粒调剖后聚合物驱动态指标变化规律。How to make some breakthroughs on current technology and technique in late polymer flooding stage, so as to increase the efficiency of polymer as well as the development effect of polymer flooding, is one key and urgent problem for the oilfield development by polymer flooding. Pre-cross linking grain profile control agent has good volume expansion behavior, and adjustable grain size, intensity and expansion multiple, which can help modify the infectivity profile effectively, improve the development effect of polymer flooding and increase the ultimate recovery. This paper has made a study on the characteristics of grain profile control in late polymer flooding stage as well as selective well technology and selective zones technology. The detailed analysis about variation rule of dynamic index of polymer flooding after grain profile control in later polymer flooding stage for North Saertu development area has carried out.
