摘要
首先利用数值模式匹配方法分别考查存在金属芯棒和介质芯棒时的测井响应；然后计算直耦信号对消所需要的接收线圈的匝数比；最后研究频率、收发线圈距及两接收线圈距对ＡＩＴ阵列感应测井成像仪中线圈系单元的径向探测深度和纵向分辨率的影响。这些结论可为ＡＩＴ阵列单元的设计提供理论依据。
fos paper investingates the logging response in the case of metal and medium mandrel by using the numerical mode matching method,respectively,and computes the circle ratio of two-receiver coils so that the total direct coupling signal in free space is close to zero. Finally,the present authores investigate the effect of freqquency. transmitter-receive interval.and two-receiver interval on radial investigation depth and vertical resolution of each coil array unit in Array Induction Imagner Tool(AIT).These results provide theoretical basis for AIT design.
