摘　　要：对FNN-3200电子罗盘在CNG储气井检测成像中的同步进行了研究。研究表明电子罗盘在检测设备中的安装位置直接影响到获得图像同步信号处理电路的复杂程度。安在静筒中需设置光电转换电路,电路较复杂;安在动筒中的处理电路较简单。两种安装方式都能得到精度较高的检测成像同步脉冲。The synchronization of FNN-3200 electronic compass in the detection and imaging of CNG gas storage well is studied. The results indicates that the installation position of electronic compass in test devices is related to the complexity of the processing circuits acquiring image syne signals. If the compass is placed in moveless tube, processing circuit needs the added photoelectric conversion circuits, which is more complicated. However, the one in mobile tube is simpler. Both can get high-precision synchronization pulse signals of detection imaging.
