阵列感应成象测井响应的探讨

Discussion on Array induction Imaging Log Response

高效曾：阵列感应成象测井响应的探讨，测井技术，１９９６（４）２０，２７１～２７６。阵列感应成象测井响应曲线是基于ＡＩＴ来集的２８条电导率曲线，经井眼校正并利用软件合成一组五条曲线。这五条曲线垂直分辨率一致，探测深度逐渐递增。每条感应响应曲线都是井深（Ｚ）和径向距离（ｒ）的函数。在应用二维反褶积把阵列信号合成测井曲线的信号处理之前，应用井眼校正后的阵列电导率完成相互间的对比。本文给出阵列感应成象测井响应的实例分析。

Based on 28 conductivity logs obtained from the AIT, the borehole corrected array measurements are combined using software to produce a set of five log curves with closely matched vertical resolution and stepwise progressive increase depths of investigation. The response characteristics of each measurement are the function of the well depth (Z) and the radial dimension(r). Cross comparisons are done using borehole corrected array conductivities before the array signals are merged into log signals by two-dimensional deconvolution. This paper presents some analysis examples of the AIT logs.
