| 中文摘要:钻进过程中，钻柱振动是不可避免的，而且钻柱产生振动的原因是多方面的。随着研究的深入，人们不仅认识到钻柱振动对钻井作业产生的负面影响，还认识到利用振动可以得到许多井下信息。运用一根钻杆模型，分析了其在不同工作状况下的振动特性，得到了钻杆在横向、纵向、扭转振动的多阶振型，以及对应的应力应变图。对照振型和应力应变图，联系钻井实践中各种钻柱失效形式，以期从中找出一些振动与钻柱失效的关联，更好地利用振动去解决生产问题。 |

| Abstract:The dill string vibration is inevitable during drilling process due to various causes. With in-depth research, it is recognized that the drill string vibration not only has negative influence on drilling operation, but also can be used to get a lot of underground information. Using a drill pipe model, the analysis was made on the vibration characteristics under different working conditions; multiple modes of transverse vibration, longitudinal vibration and torsional vibration were obtained, as well as the corresponding stress-strain diagram. The vibration modes were compared with the diagram and the consideration was also made on the drill string failure modes in order to find out the correlation between vibration and drill string failure to make vibration helpful in production. |
