Through comparison between calculation results and the real broken case of the rod-line, it is found that Model 3 can be used to simulate the working state of the screw pump rod-line well.
抽油杆的內力和應力水平與杆的“麻花”程度密切相關，模型3的模擬結果與抽油杆的實際斷裂情況相吻郃。
Working state of a screw pump rod-line is analyzed using Finite element analysis method during broken working station, and three kinds of possible mechanical models are set up.
如何降低螺杆泵抽油杆的應力水平，提高工作壽命是石油開採設備研究中一個急需解決的力學問題。
