摘　　要：针对电容阵列仪(capacitance array tool,简称CAT)在水平井多相流监测中暴露的不足,即CATView软件成像失真和油水两相流时有时漏失油相信号,首先分析了产生不足的原因,一是已有的成像算法没有充分考虑流型的特点,二是测量方式没有考虑仪器的结构特点;然后指出了流动成像算法的改进思路,提出在实际使用CAT时应添加扶正器。There existed two shortcomings of multiphase flow monitoring in horizontal wells by using capacitance array tool(CAT),one was imaging distortion of CATView software,the other was the loss of oil signal in oil-water two phase flow logging.The reasons for the shortcomings are analyzed firstly,the first is that the flow pattern is not fully considered in existing imaging algorithms,the second is that the structural character is not considered in the instrument.The ideas for the improvement of flow imaging algorithm are point out,and it is proposed that stabilizer should be used when using CAT.
