| 摘 要： | 随着油气田开发由陆地走向深海,海洋立管系统得到了充分的应用。由于立管的存在,容易导致严重段塞流的形成,引起剧烈的压力和流量波动,对下游生产设备的操作及管线的运行带来了安全隐患。为了研究海洋立管中的严重段塞流,将严重段塞流水力学模型与相平衡计算模型、温度计算模型相结合,建立了严重段塞流组分模型。研究表明,该严重段塞流组分模型的计算结果给出了合理的流动规律,可用于凝析油气管线中的严重段塞流现象的预测。同时,将计算结果与OLGA模型的模拟结果进行了对比,进一步说明了该模型的实用性,对严重段塞流的预测和控制具有一定的借鉴意义。

| Abstract: | Riser system is widely used in the oil and gas field development to the deep sea. Severe slugging which occurs in the riser system causes safety risk to the equipment and pipeline operation due to pressure and flow fluctuation. Compositional model of severe slugging was developed by combining hydraulics model and phase equilibrium model. The simulation results were reasonable. Compared with OLGA model, the deviation was acceptable, providing reference for the prediction and control of severe slugging. |
