近几年来，多相计量方面的研究工作得到了加速发展。兴趣提高的原因主要是经济性的。据估计，全世界已核实的石油和天然气储量的50％以上都是位于深度大于1000ft的水下。这样的水深就要求在技术和经济两方面都有新的进展，以便使计划变得可行。对于在深水中有经济意义的生产来说，在一些比较有希望的方法中都包含有多相计量，特别是与多相泵送相结合时。水下采油、计量以及向岸或向平台的运输，都必须考虑到过程的效率和低耗，以便尽可能地降低平台的费用。对于某些设计方案来说，有可能省去分离设备和测试管线，这将在经济上带来很大的节省。本文要研究的是多相计量中当前所使用的方法，当前的研究，以及未来的研究计划。
In recent years, research work on multiphase measurement has been accelerated. The main reason for increased interest is economic. It is estimated that more than 50% of the world’s verified oil and gas reserves are located below 1,000 feet in depth. Such water depth calls for new technological and economic advances to make the project viable. For economically profitable production in deep water, some of the more promising methods include multiphase metrology, especially when combined with heterogeneous pumping. Subsea oil production, metering, and shore-to-platform transport must take into account the efficiency and low cost of the process in order to reduce the cost of the platform as much as possible. For some designs, it is possible to dispense with the separation of equipment and test lines, which will result in significant economic savings. This article is about the methods currently in use in multiphase metrology, current research, and future research projects.
