摘　　要：近年来,海洋油气勘探开发已从浅海走向深海,甚至超深海。随着水深的增加,隔水管受力状态更加复杂,对隔水管的强度和稳定性的要求也更高。研究影响隔水管固有频率变化的各种因素,并数值计算了张力比、管长、浮力块对隔水管固有频率的影响,通过分析提出避免发生锁频共振途径,所得的结果可对深水钻井隔水管的正确设计和使用提供参考。In recent years,the offshore oil exploration and exploitation are being approached from shallow water to deepwater,even to the ultra-deepwater.As the water depth increases,the force acting on the drilling riser becomes more and more complicated and higher strength and stability are requested.Effects of top tension ratio（TTR）,the length of the riser and buoyancy modules on natural frequency were studied numerically.Approaches to avoiding resonance of the deepwater drilling riser are put forward.And the results can be referred in designing and using of deep water drilling riser.
