摘　　要：原有的激发极化测井仪只能采集到激发电场断开瞬间的二次场电位的衰减值,采集不到完整的激发极化电位随时间的衰减谱。本文介绍一种自行研制,且能够连续记录激发极化电位衰减谱的测井方法,该方法采用阵列式组合的电极结构,通过单片机控制电极系来激发和采集数据,可以采集到完整的激发极化电位衰减谱。应用该方法研制的样机已经采集到了完整的激发极化电位随时间的衰减谱,所包含的信息量远远大于传统的激发极化测井。The conventional induced polarization logging tools can only measure the secondary field potential attenuation at the time when the excitation electric field is off.It can not measure the complete induced polarization potential attenuation spectra with the time.This paper presents our own developed logging method by which the continuous induced polarization potential attenuation spectra can be recorded.The array composite electrode structure was adopted in this method,Single Chip Microcomputer was used to control the electrode for stimulating and collecting data.With this method the complete induced polarization potential attenuation spectra were measured.By using the logging prototype developed in this method the complete induced polarization potential attenuation spectra with time were measured.The information contents acquired with this method are much more than using the conventional induced polarization logging tools.
