摘　　要：电磁流动成像测井可以实时测量油井内油、气、水在流动截面上的分布图像,进一步通过图像分析识别流体的流型,提取流动参量。根据油井内多相流体的流动特征和电磁流动成像测井原理,解析测量重建的流动图像,在分辨流型的基础上得到各相持率,然后通过相关计算获得各相的流动速度,从而获取流体动力学参量。Electromagnetic imaging well logging can get the real-time distribution sections of the oil, gas and water in well, and identify flow regime by image, which is followed by calculating flow parameters. On the basis of the flow characteristics of the multiphase flow and the principles of electromagnetic imaging well logging, how to analyze the re.constructed flow images and the methods to obtain the hydrokinetics parameters which include the hold- up of each phase after identifying the flow regimes and the velocity calculated by cross-correlation are presented.
