As one of the main types of deepwater risers,hybrid riser is considered to have several unique advantages when compared with other riser types,such as reduced coupling motions between floating production unit and riser system,and lower fatigue damage etc.This paper presents an introduction to the general structure,characteristic and future of the hybrid riser,and mainly focuses on the design and selection of some key components of hybrid riser.Based on the unique advantages and successful cases around the world,especially in West of Africa,hybrid riser could provide a potential solution for the exploration of oil and gas fields in South China Sea.%混合立管是深水油气田开发中常见的主要立管类型之一,在降低浮式生产装置和立管系统的运动耦合度以及减小疲劳损伤等方面具有独特的优势.本文介绍了混合立管系统的总体组成、特点和未来发展趋势,并主要就其部分关键部件的设计和选型技术进行了论述.混合立管的特点及其在世界范围内尤其是西非海域的成功案例,可为我国开发南海深水油气田提供重要参考.
