, 2009 分岔管路作为一种新型管式分离部件已经在油田上得到了初步应用,与沉降罐和卧式分离器等传统分离设备相比具有分离效率高、体积紧凑、压降损失小等优点。不同入口条件和运行工况下,多相介质在分岔管路内的相分布特性对其分离性能和流动特性有显著的影响,目前这方面的研究还需深入和完善。本研究通过室内实验观察了分岔接头和分支管路内的相分布情况,采用VOF模型中的PLIC方法对分岔管路内的油水相界面进行了数值重构,计算中考虑了混合流速、相含率和流量配比等参数的影响,模拟结果与室内实验符合较好。计算发现 ...

, 2017 油水两相流经T型管时经常会不可避免地出现相分配不均现象,可以利用这个流动特性来实现两相预分离。结合浅池原理,本研究提出了一种偏心T型套管的新型设计,进一步提高油水分离效果。该分离系统包括上、下两层偏心套管,并通过两个立管相连通,且上外管顶端固接沿轴向延伸的浮油管。流体通过内管底部的狭长开缝在内外管之间流动,浮油通过上外管顶部开孔进入浮油管。这种设计能够降低雷诺数从而易于形成油水分层流动,而且狭长开缝能够极大地降低湍流强度,避免油水分离后重新掺混。文中研究了入口流型、油相速度、水相速度 ...
