本文介绍了印度Sanand油田采用聚合物驱技术提高采收率的具体做法，详细阐明了聚合物驱机理，在广泛的室内试验的基础上，筛选出了适合于Sanand油田的聚合物类型和最佳浓度。通过先进的先导性试验、先导性扩大试验，最后转入油田规模应用的方法。保证了聚合物驱的经济性。应得结果表明，采收率水平大大提高，增产效果非常明显。
This paper introduces the practice of using polymer flooding technology to improve oil recovery in Sanand oil field in India, and expounds the mechanism of polymer flooding in detail. Based on a wide range of laboratory tests, the polymer type and the optimum for Sanand oil field are screened out concentration. Through advanced pilot tests, pilot expansion of the test, and finally transferred to the oilfield scale application methods. Guaranteed polymer flooding economy. Deserved results show that the level of recovery has greatly improved, the effect of increasing production is very obvious.
