摘　　要：应用疲劳强度理论和累积损伤理论,利用对使用不同年限抽油杆的常规机械性能的测试结果,由抽油杆的静特性去推测其疲劳特性。建立了抽油杆损伤因子的概念,提出了在用抽油杆服役期限的确定方法,为科学、合理地使用抽油杆提供了理论依据。The fatigue properties of sucker sods are predicted by its static properties with fatigue strength theory and cumulative damage theory according to the measurement result of conventional mechanical properties of sucker sods with different service periods. The conception of cumulative damage factor for sucker sods is established, and a method for determining service deadline of sucker sods in use is put forward, which provides a theoretical basis for scientifically and rationally using sucker sods.

关 键 词：抽油杆 静特性 疲劳特性 累积损伤 服役期限
