With the development of the deepwater gas field, the flow assurance is important for the deepwater gas pipeline. In this paper, the issues and measures of the deepwater flow assurance are analyzed hy the software of OLGA and the gas pipeline of the Liwan3-1 gas field is researched as an example. The research conclusions will be expected as reference to the design of deep water gas pipeline.%由于水深和距离的影响,深水天然气管道的流动安全保障问题突出.本文以荔湾3-1深水气田天然气管道设计为例,利用OLGA动态模拟软件对深水天然气管道流动安全保障的几种典型工况进行分析,探讨了深水天然气管道设计中须要关注的问题以及相应的解决措施,以期对今后深水天然气管道设计提供参考.
