| 摘 要： | 以油、气、水为试验介质，研究了油气水多相流体在水平管中的流型特征。通过测取水平管内油气水多相流流动的试验段压力降脉动信号，运用扩散分析方法对所测压力降脉动信号进行分析。分析表明，不同流型的信号序列其数值分析的结果具有不同的数值特征，反映了不同多相流流型的流动机帛，因此可用于多相流流型识别。

| Abstract: | In this paper,a study on the characteristic of flow regime for oil-gas-water multiphase flow in horizontal pipeline has been made taken oil ,gas and water as testing medium. The pressure drop fluctuation signals of oil-gas-water multiphase flow in horizontal test section have been measured. The diffusion analysis methods are proposed to analyze the pressure fluctuation signals. It has shown that results are found distinct quantity characteristic of the signals corresponding to different multiphase flow regimes. The results implicate the system of multiphase flow regimes. Therefore,the diffusion method may be adopted to identify the flow regime. Owing to the experiment,the method is very effective and easy to write a simple code for the on-line analysis. |
