摘要
概述了超高强度抽油杆的特点,将其与其他抽油杆进行了对比分析;给出了超高强度抽油杆P-S-N曲线的定义、试验研究方法;通过试验,得出了3个应力水平下,超高强度抽油杆试样的循环次数;用概率统计法对试验数据进行了处理,得到了P-S-N曲线。有了超高强度抽油杆的P-S-N曲线,就可以据此对各种超高强度抽油杆进行检验,从而避免或减少抽油杆断裂事故的发生。
The characteristics of sucker rod with super high strength are introduced and compared. The definition and test method of P-S-N curves for sucker rod with super high strength are given. The circulating cycles under 3 load levels are obtained. The P-S-N curves are made by statistic treatment of the test data. Sucker rod with super high strength can be tested according to the curves, thus avoiding or reducing the failure of the sucker rod.
