摘要: 钻柱振动是导致钻柱失效、疲劳损坏的主要原因,结合钻柱动力学理论以及运动微分方程,并通过ANSYS软件对大位移井钻柱的纵向振动模型的建立和分析做了合理的假设,经过ANSYS分析计算得出大位移井全井段钻柱的振动规律。

Abstract: Drill string vibration is the main reason for its failure and fatigue damage. Employing the dynamics theory and its basic differential equations with a reasonable assumption, the longitudinal vibration model of the drill string is established and analyzed by means of ANSYS code. The rule of the drill string vibration is obtained. Results of this work may provide some guidance for design and operation of the drill string.

Key words: vibration and wave, drill string, longitudinal vibration, absorber, modal analysis, ANSYS
