摘　　要：持水率探测器是生产测井检测油井中原油持水率的关键仪器。针对我国油田高含水的现状,为了解决常规持水率计在高含水条件下分辨率低的问题,基于已有的理论分析结果,进行了高频电磁波持水率探测器的试验研究。给出了在持水率全范围变化条件下,电磁波在不同尺寸结构探测器上的信号特性。试验结果与已有的理论分析基本一致,表明按照一定结构要求设计的探测器能够实现持水率全范围高分辨率连续测量,相关的数据和结论对电磁波持水率探测器的结构设计有实际参考价值。The water holdup detector was the key apparatus used to detect water holdup of crude oil in production logging.According to the present situation of high water-cut in our oilfields and to solve the problem of low resolution in the conventional water holdup instrument under the condition of high water cut,and based on the theoretical analysis result in literature,an experimental study was carried out for high frequency electromagnetic wave water holdup detector.The signal characteristics of electromagnetic wave in different sizes and structures of detectors are proposed in the full range of water holdup changing conditions.Experimental results are basic consistent with the theoretical analysis of the literature,it shows that according to the certain structural design requirements,the detector can realize the full range and high resolution continuous measurement of water holdup.The relevant data and conclusion provide practical reference to the structural design of the electromagnetic wave water holdup detector.
