摘要:

研究了连续油管柱内流体的液动压力对连续油管柱纵向振动的影响问题。建立了一个考虑流体液动压力的连续油管柱纵向振动微分方程,并给出了这种情况下连续油管柱纵向振动的频率方程,是探讨连续油管柱内流体对连续油管柱纵向振动规律影响的一个尝试。

Abstract: This paper studies the affection that the flowing force of fluid inside coiled tubing is correlated to longitudinal vibration of coiled tubing. After building a differential equation for longitudinal vibration of coiled tubing considering fluid hydrodynamic force, the frequency equation on longitudinal vibration of coiled tubing is obtained. It is an attempt to explore the affection of fluid inside coiled tubing on law of longitudinal vibration of coiled tubing.

Key words: Tubing failure, Fatigue failure, Tubing string, Vibration, Flowing pressure
