在石油行业中，现在不需将通流中的油、水、气相组分进行分离，即可利用多相测量技术测出油、水、气的含量。随着这项技术的不断改进，多相测量设备投放市场的数量也在不断地增加。这篇文章讲述了多相测量技术的各种用途、工艺性能．发展进程以及作业人员为使该技术达到使用可靠性所作的一切尝试，并概括了当前全球用于作业的多相测室设备总数量。 In the oil industry, oil, water and gas levels can now be measured using multiphase measurements without the need to separate the oil, water, and gas components in the flow. As the technology continues to improve, the number of multiphase measurement devices on the market is also constantly increasing. This article describes the various uses of multiphase measurement technology, process performance. Development process and all attempts made by the operators to ensure the reliability of the technology and summarizes the current global total number of multi-phase measuring equipment used for operations.
