| 摘 要： | 随着三次采油技术应用规模的不断扩大，聚合物驱油技术己成为油田开发的必然选择。聚合物驱油方法是在注入水中添加一定浓度聚合物，从而改变注入水的黏弹性能来提高注水波及体积和驱替效率的一种采油方法。可见，聚合物驱油技术本质就是聚合物溶液的黏弹效应，依据油田开发的实际需求，通过室内实验和理论分析，对不同种类驱油用聚合物分子形态及其黏弹性能进行了系统研究与分析，结果表明不同种类聚合物溶液黏弹性和流变性差异较大，ZKY618—2和DQ—KY聚合物性能相对较优。

| Abstract: | With the expanding application of tertiary oil recovery technology, the polymer flcooting technology has become an inevitable choice for oilfield development. Polymer flooding method is to add a certain concentration of polymer into the water, thus change the viscoelastic injection water to improve water swept volume and the efficiency of oil displacement. The essence of polymer flooding technology is the viscoelastic effects of polymer solution, based on our actual needs of oil field development, through laboratory experiments and theoretical analysis, systematic research and analysis was done using different types of polymer on its viscoelastic properties. The results showed that viscoelasticity and rheology of different types of polymer solution is quite different, ＂ZKY618-2＂ and ＂DQ-KY＂ are relatively better in performance. |
