Aiming at the problem of real-time measurement of on-line multiphase flow in oilfield production process,this paper presents a quantitative multiphase flow measurement method for oil,gas and water based on Multi-sensor and SVR algorithm. The key parameters of multiphase flow,such as gas phase,liquid phase flow and liquid phase water content(wlr),are measured by advanced venturi and microwave measurement methods,and combined with the machine learning algorithm based on support vector regression(SVR) to construct and evaluate the measurement model.The evaluation results show that the measurement accuracy of the multi-phase flow measurement model proposed in this paper can meet the requirements of industrial multi-phase flow measurement,with measurement errors of gas phase,liquid phase flow and liquid phase water content less than 10%.This study provides a new technical for on-line real-time measurement in oil- gas production process.
