2、e.尽管由于水下采油树，隔水管和脐带方面技术的进步，水下部署已经成为了可能，但是水下处理依然是比较困难的地方。无论如何描述水下分离，回注或增压，水下处理还是在全世界范围内大大的帮助了海洋的开发。GreaterGorgonSubseaDevelopmentWithproductionequipmentlocatedontheseafloorratherthanonafixedorfloatingplatform,subseaprocessingprovidesalessexpensivesolutionformyriadoffshoreenv

4、increaseproductionfrommatureormarginalfields.由于海床上的生产设备不像固定式或浮式平台，它可以提供更为廉价的海上解决方案。最初设想是为了克服深水极端环境，水下处理对于严酷环境下的油田已经成为切实可行的方案，毕竟水面设备还是风险很大。另外，水下处理还可用于成熟油田或边缘油田的应急增产。SubseaProcessingFunctionsSubseaprocessingcanencompassanumberofdifferentprocessestohelpreducethecostandcomplex

6、低海洋油田的开发成本和难度。主要的水下处理包括海底除水，回注或处理，井内流体的单相和多相增压，砂及固体分离，气液分离和增压，气体处理和压缩。TheTordisFieldSeperatorSource:GreenlandGroupSavingspaceonoffshoreproductionfacilities,separationofwater,sandandgascannowbeperformedsubsea.Subseaseparationreducestheamountofproductiontransferredfromthesea

8、水下生产设备节省空间，水砂气分离可以在水下进行。水下分离减少了从海床到水面产出物的转移，克服了处理量的瓶颈。而且，通过分离掉不想要的成分，流动管线和隔水管也不许将其举升到水面设备
