| 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。

| Abstract: | 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 |
