针对传统油井多相流地面分离计量方法的缺点，研究出了经旋流气相分离后油水两相流参数连续测量方法。基于低流量条件下油、水两相分离特点，在一个容积已知的环形空间内，利用仪器上位于油、水区域的两个阀门的不断切换，自动测量油相和水相排出该空间所用的时间来计算油井油水两相流条件下的流量和含水率。“,”Aimed at the shortcomings of traditional oil-well multiphase flow separation and metering method above the ground,a continuous metering method of oil-well two-phase flow after cyclonic gas-separation is studied in this paper.The flow rate and water content in oil wells can be calculated by this method.
