摘要: 随着油气开发区域逐渐由陆地向海洋、由浅海向深海发展，油气生产中面临着段塞流等危及管道安全和海洋环境的问题，工程设计中有必要通过多相流模拟软件对深海油气田生产过程进行动态模拟及风险预测。借助巴西某深海卧底–悬链线立管系统，利用OLGA软件对严重段塞流进行敏感性分析，模拟不同控制方法并提出相应的适用情况，总结液塞长度、压力波动幅值及周期等参数变化规律，可为深海油田实际工程中严重段塞流的预测及防治提供理论依据，具有工程实际意义。
Abstract: In offshore oil and gas production, there are problems such as slugs that endanger the safety of pipelines and the marine environment with the gradual development of oil and gas development area from land to sea and from shallow sea to deep sea, therefor it is necessary to conduct dynamic simulation and risk prediction of deep-sea oil and gas field production process through multiphase flow simulation software in engineering design. With the help of an actual deep-sea pipeline-catenary riser system abroad, the sensitivity analysis of severe slugging flow is carried out by using OLGA software. Different control methods are simulated and the corresponding applicable conditions are put forward. The variation rules of slug length, pressure fluctuation amplitude and period are summarized. It could provide a theoretical basis for the prediction and prevention of severe slugging flow in the actual engineering of deep-sea oil field, and have practical engineering significance.
