摘　　要：随着海洋石油工业的发展,从20世纪70年代的浅海立管到21世纪的深海立管,海洋管道发展了多种新的形式,如悬链线立管、S形立管等。对于各种混输立管系统,严重段塞流等不稳定流动会造成设备损坏,严重影响安全生产。因此,实现立管流动的准确模拟,通过合理设计和科学运行控制、消除严重段塞流,具有重要意义。综述了国内外海洋混输立管流动模拟的研究成果,包括L形立管和柔性立管的实验研究、模型模拟及软件模拟的主要进展。指出了当前研究中存在的问题及未来的研究方向,可为进一步开展立管流动模拟研究提供参考。With the development of offshore petroleum industry from shallow sea risers in 1970's to deep sea risers in the 21 st century,marine risers have been developed into many types,such as catenary risers,S-shaped risers,etc.As for risers in different mixed transferring systems,the unstable flow,such as severe slug flow,can cause serious equipment damage and thus can have a great impact on production.Therefore,the correct simulation of risers is equally as significant as the proper design,and scientific operation control and elimination of severe slug flow.This paper summarizes the study results in flow simulation of marine mixed transport risers at home and abroad,including the main progress in experimental study,model simulation and software simulation of L-risers and flexible risers.The authors reveal some problems in current study and future study direction,and provide reference to further simulation study in riser flow.
