摘　　要：随着水深的增加,隔水管受力状态更加复杂,增加了强度和稳定性的分析难度。考虑了隔水管受到内外流体流动及轴力共同作用,并运用达朗贝尔原理对微元管段进行受力分析,导出隔水管的横向振动偏微分方程。分析了影响隔水管横向振动的因素,所得到的结论可为钻井隔水管的正确设计和使用提供参考。As the water depth increases, the force acting on the drilling riser becomes more and more complicate and higher strength and stability are requested. Considering the internal flowing mud, the external environmental loads and the axial force, the lateral vibration differential equation of a deepwater drilling riser was derived by mean of d＇Alembert principle. The corresponding boundary conditions have been put forwarded and a numerical model for deepwater drilling riser is established. And the results can be referred in designing and using of deep water drilling riser.
