摘要
分析认为， 钻柱轴向变形主要受轴向力、液柱压力和螺旋屈曲等因素影响。给出了二维设计井眼中钻柱受轴向力和液柱压力引起的轴向变形计算方法，还讨论了钻柱螺旋屈曲对其轴向变形的影响，并给出了算例分析。
It is analyzed that the axial deformation of drill string is mainly affected by axial force, hydrostatic pressure, spiral buckle etc. The calculation methods of axial deformation of drill string caused by axial force and hydrostatic pressure in 2D well plan are provided. The effect of spiral buckle of drill string on its axial deformation is also discussed. Furthermore, the case history is provided.
