摘要
卡钻事故在石油钻井工业中时有发生,计算震击动载荷的方法各不相同。结合现场实例,在合理假设的基础上,建立有限元分析模型,计算得出震击动载荷是上提拉力的3.3倍。该结果和现场实际非常接近,对震击器的使用有重要的指导价值。
Sticking namic load method incidents in oil drilling industry happen constantly. And calculating the dy varies. According to a scene example, lished on proper assumption and force. The results accord with the for practical jarring operation. finite element analysis model was estab dynamic load was 3. 3 times than that of calculated upward fields very much. And it can give some important instruction
