摘　　要：随着立管长度的增加,海洋立管间的干涉风险也在增大,在深水油气田开发的早期就应关注立管干涉问题。立管干涉包含了复杂的物理现象,其中水动力相互作用对于众多立管系统的干涉分析来说不可忽略。该文主要根据DNV-RP-F203规范介绍了基于水动力相互作用的深水立管干涉分析方法,给出了深水立管干涉分析的设计流程,探讨了立管干涉的可接受标准,为深水立管设计分析提供借鉴。The risk of interference between marine risers increases with increasing riser length. Riser interference should be addressed in early stages of the deepwater riser design process. Riser interference comprises complex physical phenomena including hydrodynamic in- teraction which should not be neglected for most of riser system interference analysis. In this paper, deepwater riser interference analysis approach based on the hydrodynamic interaction is introduced according to DNV-RP-F203, the corresponding design procedure is given and the acceptance criterion of interference analysis is discussed, which provide reference for deepwater riser interference analysis.
