摘　　要：叙述了利用两相流体的混合不均匀性来测量流体流量的频率分析法。基于流体分散相的含水扰动信号中含有流体密度信息和流速信息，通过对扰动信号的高频分量进行相应的数据处理，将流速信息取出，使单一的含水传感器具有一定的流量测量能力。通过室内模拟井试验证实了这种方法的可行性。A frequency analysis method is presented in this paper for measuring the flowrate of oilwater twophase liquid mixtures. Perturbation signal at the output of a watercut transducer placed in a well contains information about fluid density and fluid velocity.Data processing is made to the high frequency component of the perturbation signal to acquire fluid velocity, thus, making the watercut transducer able to measure the fluid flowrate.The feasibility of this method is proved by the indoor simulation experiments. And the experiment data of flowrate from model wells is analysed.
