摘要:

在综合分析抽油杆破坏形式的基础上,肯定了采油过程中抽油杆扭转振动的客观存在,分析了抽油杆产生扭转振动的原因。根据分析的结果初步建立了抽油杆扭转振动的上下端边界条件,为抽油杆的扭转分析和扭转破坏的量化分析奠定了一定的理论基础。

关键词: 抽油杆, 扭转振动, 边界条件, 分析

Abstract:

On the basis of analyzing the failure forms of the sucker rod, the existence of the torsional vibration of the sucker rod was approved and its reason was found out. The up and down boundary and condition of the torsional vibration of the sucker rod was established in the light of the results. It provided the theoretical supports for the torsional analysis and its failure of the sucker rod.

Key words: sucker rod, torsional vibration, boundary condition, analysis
