摘要
带扶正器下部钻柱组合的失效是钻柱失效的一种很重要的类型。现从钻柱动力学的角度研究带扶正器下部钻柱组合失效的力学机理。带扶正器下部钻柱组合失效的主要原因有二：一是下部钻柱的质量不平衡引起横向振动；二是钻柱进动和碰摩。文后提出了防止和减少带扶正器下部钻柱组合失效的建议和措施。
The failure of BHA with stabilizers is important among drilling string failures.Its failure mechanism is studied based on drilling string dynamic mechanism.The major reasons are:the lateral vibration caused by the mass imbalance force,the drilling string whirling and collision.Measures to prevent or reduce the failures are suggested.
