摘要
分析了在井下完成自然电位测井仪数据采集的优点.设计了以AT89C 52单片机为控制单元的自然电位测井仪数据采集系统.详细介绍了前置放大、低通滤波、模数转换等电路模块的设计思路及注意事项.
The advantages of the downhole data cellection by spontaneous potential logging instrument are analyzed.The data acquisition system of spontaneous potential logging instrument is designed by using AT89C 52 microcontroller as the control unit.The design ideas on pre-amplification,low-pass filter,analog-digital conversion and other circuit modules are introduced in detail.
