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。
Through the systematic experimental research, the influence rule of the casing cyclone centralizer on the annulus flow field is obtained, and the influence of the cyclone on displacement efficiency is analyzed. It is concluded that the cyclone centralizer can improve the efficiency more effectively than the strip centralizer. Cementing efficiency and cementing quality.
