| 摘 要： | 从理论上研究了钻井液在钻柱弹性振动下的液动压力对钻柱纵向振动的影响,建立了考虑钻井液液动压力的钻柱纵向振动微分方程,并给出了这种情况下钻柱纵向振动的频率方程。

| Abstract: | The influence of the hydrodynamic pressure of drill fluid caused by elastic vibration of drillstring on the longitudinal vibration of drillstring is studied. The differential equation of the longitudinal vibration of drillstring, taking the hydrodynamic pressure of drill fluid into account, is established,and the frequency equation for the longitudinal vibration of drillstring is presented. |
