Abstract
用于测量原油的API比重的设备，其包括：用于油的管道(1)；在管道中的热电偶(4)，所述热电偶(4)用于测量与其接触的油的温度；在管道中的蓝宝石窗(3)；用于通过窗测量油之温度的红外温度计(5，6)；以及用于比较通过温度计测得的温度之测量结果以获得原油的发射率度量并且从而获得其API比重的装置(20)。
Description
技术领域
本发明涉及原油的密度的测量，并且具体涉及原油的API比重的测量。
背景技术
美国石油学会比重，或API比重，是石油液体与水相比有多重或有多轻的度量(measure)。其通过以下线性关系与具体比重(SG)相关联：API比重＝141.5/(SG)-131.5，使得如果液体的API比重大于10，则液体比水更轻并且漂浮在水上；如果液体的API比重小于10，则液体比水更重并且下沉。
API比重用于比较石油液体的相对密度。其定义是温度为15.6℃时的密度。API比重越高，原油越轻。“轻质原油”通常具有38度或更高的API比重，“重质原油”具有22度或更低的API比重。API比重在22度至38度之间的原油通常被称为“中质原油(medium crude)”。还在硫含量的方面对原油进行表征。“低硫”原油(crude)通常被定义为硫含量小于0.5％的油，而“含硫”原油的硫含量为大于0.5％。
原油的质量决定了实现炼油厂看作产品的最佳混合所需要的加工和转化的水平。轻质低硫原油比重质含硫原油更昂贵，原因是对于生产给定的最终石油产品而言，轻质低硫原油与重质含硫原油相比需要较少的加工。
因此，用于测量API比重的在线远程方法对于油工业是有用的。
根据黑体辐射定律，所有物体在大于绝对零度的情况下均发射红外辐射。远程检测物体的温度需要知道该物体的发射率。发射率是表示材料发射热辐射的能力的术语。各种材料具有不同的发射率。材料的发射率可以在理论上的0(完全不发射)至同样理论上的1(完全发射)的范围内；发射率经常随温度变化。黑体是一种在其接触温度下辐射红外辐射的理论物体。如果在黑体辐射体上的热电偶的读数是50℃，则黑体将释放的辐射也会是50℃。因此，真正的黑体的发射率将是1。
发明内容
本发明依赖于以下事实：原油的发射率与其API比重相关。只要发射率的测量足够精确，其就会提供原油之API比重的合理指标。原油的发射率随着API比重变化，使得能够根据本发明通过比较原油温度测量的不同方法来检测API比重的变化。
在本发明的优选实施方案中，接触式温度计(例如高度精确的热电偶温度传感器)测量原油的实际温度。可以使用具有适当发射率的相同的原油样品来测量相同的温度以校准第二远程红外传感器。当原油流过这两个传感器时，在远程红外传感器(不考虑校准漂移和准确度限制)与热电偶传感器的温度测量之间的任意不同指示原油发射率的改变并且因而指示API比重的改变。
附图说明
图1是温差(differential temperature)测量的示意图。
图2是测量系统的示意性表示。
图3是根据本发明的校准方法和测量方法的示意图。
具体实施方式
图1是用于估计原油密度的温差测量仪器的示意图。在可以使原油2流过的管道1例如出油管(flow line)上(或在井下测量仪器中)的合适位置处设置有窗3使得可以对出油管内的原油进行光学测量。
在紧邻窗3处还安装有接触式温度计4(例如，热电偶)使得接触式温度计4的感测元件与原油接触。红外温度计设置于能够通过窗3检测原油温度的位置。红外温度计可以是在一个仪器中的发射器和接收器，或者替代地可以被布置成在第二仪器中带有接收器6的发射器5(如所示的)，两者都通过蓝宝石窗观测原油。使用透镜7可以将来自红外温度计的红外发射聚焦到原油上，透镜7可以由锗制成。红外温度计设置在与管道1相邻并且覆盖窗3的壳体8中。
窗3优选地由蓝宝石玻璃制成，该蓝宝石玻璃对于该应用的窗的具有若干有利特性。蓝宝石玻璃是氧化铝(Al2O3)单晶。蓝宝石玻璃在机械上非常坚固，具有高拉伸强度(400MPa)和高弹性模量(345GPa)，使其非常耐磨并且耐冲击。蓝宝石玻璃是热稳定的，直到温度超过2000℃为止其机械性能和光学性能不变。蓝宝石玻璃具有优良的透射性能，透射窗从190nm至5000nm(在1mm厚的情况下)，使其既适用于近紫外荧光激发又适用于红外应用。
红外辐射是一种波长比可见光长、波段在大约从780nm至300μm(取决于分类)的电磁辐射。具有透射窗从190nm至大约5μm的蓝宝石窗仅适用于使近红外波段(780nm至3μm)中的红外辐射和一些中红外波段(3μm至50μm)通过。锗窗为红外波长的透射提供了最佳选择。然而，目前可获得的锗窗的机械性能对于在出油管中使用不理想。
图2以简化形式示出了根据本发明的系统。在比较与计算电路20中比较通过接触式温度计4和红外温度计5&6测量的温度，所述比较与计算电路20是根据(例如)将发射率与API比重联系起来的表而进行编程的。比较与计算电路可以在设备壳体内。或者，可以通过例如线缆将表示测量结果的信号发送至远程位置以进行处理。
图3示意性地示出了根据本发明的校准方法和测量方法。
在图3中的步骤30、步骤31和步骤32表示至少红外温度计的校准。可以选择原油的已知样品以校准接触式传感器和红外传感器两者。该油样品将是某些标准品并且在将系统布置在海底之前完成。假设该校准样品在15.6摄氏度的API比重为30。该温度便于使用，原因是API比重是在该温度下定义的。在使用该样品的情况下通过接触式温度计(必要时经过校准)指示的温度td为15.6℃，并且红外温度计被校准成使得其温度读数ti同样为15.6℃。实践中，红外温度计可以具有对红外温度计所观测的样品之发射率进行补偿的比例因子。
在图3中的步骤33和步骤34表示借助接触式温度计和红外温度计测量在管道即出油管1中流动原油的温度。经过这两个温度计的原油具有不同的密度。如果原油的密度与30的API不同，则该原油样品的发射率与校准样品的发射率不同。然而，红外温度计基于以下假设测量温度：td与ti之间的差d与其在校准样品中时是相同的。所以来自原油的红外辐射与校准的红外辐射水平不同。因此，通过红外温度计测量的温度ti与通过接触式温度计测量的温度td将不同。检测该差(步骤35)并且使其与原油的发射率联系起来并且从而与油的API比重联系起来。获得发射率的值(步骤36)并且将其转换成API比重的值(步骤37)。
研究表明，对于典型的原油样品，发射率随密度的变化小且在一定范围内变动，所以温度计必须非常准确并且非常稳定。
