Description

一种改进分离的管子分离器
技术领域
本发明涉及一种管子分离器，用于分离流体，例如分离油、气体和水，该管子分离器与从海床下面的地层提取和生产油和天然气相关联，包括一个延伸的、管子分离器壳体，该管子分离器壳体在输入端和输出端具有基本上与运输管子的直径相等的直径，管子分离器与此运输管子连接，一个旋流器设置在分离器壳体的上游，用于分离任何存在的气体，以及一个静电聚结器安排成与管子分离器连接。
背景技术
申请人自己的挪威专利申请19994244、20015048、20016216、20020619和20023919描述现有技术的管子分离器，使用于在海床上，在地面上，在一个平台或类似物上，分离油、水和/或井下气体，尤其是挪威专利申请No.20023919示出的一个解决方案，在其中，一个单独的紧凑的静电聚结器用于与管子分离器连接。离开管子分离器的油流移动至管子分离器下游的聚结器，以及随后至另一个油/水分离器，它清除在管子分离器内分离后的剩余的水。这种现有技术解决方案特殊地设计用于，但不局限于从油相清除水至水分为0.5％的中重级油品，并且使用一个旋流器或其它类型的气体/流体分离器以清除管子分离器之前的气体。
此解决方案要求一个附加的分离器，它是复杂的和昂贵的，以及聚结器本身是一个垂直类型的，不能够以普通的方式扩孔或用清管器清理(清洗)。这点代表现有技术解决方案的缺点。
发明内容
本发明提供一个相当简单的分离解决方案，其中可以避免上述的缺点。本发明的特征在于，静电聚结器结合和组成分离器壳体的一个整体化部分，如所附权利要求1所述。
从属权利要求2-5指出本发明的其它优点。
附图说明
本发明在下面将参照附图更详细地说明，附图中：
图1示出按照本发明的一个管子分离器的一个简单的草图；
图2示出图1内的分离器在聚结器区域的一个放大部分的一个横剖面图a)和一个纵剖面图b)。
具体实施方式
图1所示的解决方案包括一个管形分离器壳体1；设置在分离器壳体的下游，用于通过分离器壳体流通的流体(油/水)内的水相的一个液体密封件6；带有一个用于分离的水的输出口8的排水器件7；设置在分离器壳体的上游并与一个油井口9连接的一个管道除垢器组5；连接油井口至分离器壳体1的一条连接管10；以及用于分离器下游的油的一条运输管11。本发明的特点是，一个聚结器4结合至分离器壳体1，成为一个整体化单元。聚结器方便地设置在离开分离器壳体的输入口一个距离为分离器壳体长度的1/3至1/2之间。然而，它的位置并不局限于该范围。图2示出分离器壳体的一部分的放大的横剖面图和纵剖面图，在此区域结合了聚结器。如图内所示，聚结器4包括一个上电极12和一个下电极13，它们优选地包容在分离器壳体的壁14内的绝缘材料内。这些电极设计为对聚结器施加(不更详细地显示)一个有利的电压“V”(交流电压)，以产生一个电场，来增加从流动通过分离器的流体(油和水)分离水。如图1所示，一个旋流器3(或其它合适的气体/液体分离器)设置在分离器壳体1的上游，以便从油井9产生的流体内清除任何气体。清除气体的目的是避免它降低聚结器的作用，因为气体是不良的电导体。另一个目的是防止在分离器内形成堵塞流。
按照本发明的分离器解决方案的工作方法如下：
流体，即产生的气体，油和水首先传送至旋流器3，在此处大部分气体被清除，以及继续在一条单独的管子9内传送，有可能重新引入分离器后面的运输管11。
它可能含有少量的气体的流体相，引入分离器壳体1。自由的水将迅速地分离并形成在油相下面的一个水相。气泡将收集在分离器管子的顶部，并根据它们的浓度形成一个自由气体相。当聚结分离已经完成(也就是水相在底部，带有小油滴的油相在中部，以及有可能一个薄的气体相在顶部)，流体传送进入集成的聚结器4。
在聚结器4内，一个将产生基本上越过油区域的电压降，因为水区域导电，以及气体区域也具有良好的导电性。
越过油区域(交流电)的电压降产生增加的液滴聚结以及使油/水界面不稳定。在流体再次进入管子分离器元件1之后，水滴尺寸长大，迅速地分离。
在聚结器4下游的分离器元件内，聚结的水滴将被分离出和收集在收集单元7内，在此处水通过管子8排出。油将流动通过水密封件6至运输管11。
如在权利要求书内所限定的本发明不应局限于以上所示和说明的实例。分离器1可以配置两个或多个聚结器4，在分离器元件1内串联排列。这点可能尤其与难分离的油品相关，比如重油品。
旋流器3也可以位于不同于图1内所示在油井口的位置。已经证明，有利的是将旋流器与能对流体引起高剪力的设备连接在一起放置，因为这样产生良好的分离条件。然而也可以在分离器远离油井口的情况下，相应地放置旋流器在分离器的入口附近处。
