摘　　要：通过研究基于科氏流量计的气液两相流计量技术,提出了科氏流量计的凝析天然气测量模型。该模型较好地表征了科氏流量计的振动频率与阻尼系数的变化规律、振动管与两相流体之间的相对运动关系等。利用E+H公司的微弯科氏流量计开展了一系列试验研究,并结合试验结果对流量计的参数波动特性、安装形式、两相混合物密度测量和质量流量测量等问题进行了深入分析。分析结果为利用科氏流量计实现凝析天然气的高精度计量奠定了基础。The research works of Coriolis meter in two-phase flow metering were reviewed, a new model of Coriolis meter for wet gas metering was proposed. The variational characteristics of Coriolis meter＇ s parameters, such as damping, vibration frequency and the interactions between Coriolis tube and two-phase flow could be explained very well based on the proposed model. A serious of experiments was carried out and some primary experimental results were analyzed, which includes the statistical features of Coriolis meter＇ s parameter, the installation methods and the output of Coriolis meter. All of the works laid the foundation for accurately metering wet gas flow by Coriolis meter.
