摘要
通过系统的实验研究，得出使用套管旋流扶正器对环空流场的影响规律，分析了旋流对顶替效率的影响情况，认为旋流扶正器比条形扶正器能更有效地提高固井效率和固井质量。
Operation machanism of whirler casing centralizer and its effect on displacement efficiency are analysed by experiment.A conclusion is drawn which whirler casing centralizer can improve annular displacement more efficiently than bar-like casing centralizers.
