摘要

在大斜度、水平井环境中检测原油持水率的空间分布信息一直是个难题。文章分析了阵列式电磁波持水率探测器的设计需求，讨论了实现该技术方案的关键问题，在此基础上，通过提高电磁波的频率和减小探测器的尺寸等方法，提出了阵列式探测器的设计方案。理论分析和实验结果表明该方案可以用于检测大斜度井的持水率空间分布信息，适用于国内大斜度井的工程需求，相关的数据和结论对阵列电磁波持水率探测器的结构设计有实际参考价值。%The water holdup space distribution information of crude oil in the environment of highly deviated and horizontal wells has always been a problem,this paper analyses the design requirements for electromagnetic wave water holdup array detectors,discusses the key prob-lems to realize the scheme,and on this basis,put forward the design scheme of array detectors by increasing the frequency of electromagnetic wave and reduce the size of the detector,and other methods. Theoretical analysis and experimental results show that the scheme can be used to detect water holdup spatial distribution information of the highly deviated wells,it is applicable to the engineering needs of the domestic highly deviated wells,and the relevant data and conclusions have practical application value to the structure design of the electromagnetic wave water holdup array detectors.
