抗干扰技术在数据采集过程中的应用

Application of anti-interference technology in data collection process

针对油田环空找水测试中的一个共性问题 ,即磁信号与井温信号之间的相互干扰 ,文章阐述了在信号传输采集过程中信号抗干扰的基本方法 ,并针对现场两路 (或多路 )不同特性的信号互相干扰的问题 ,介绍了采用滤波手段对信号进行处理后采集的方法 ,有效地抑制了干扰信号 ,使有用信号顺利通过 ,提高了有用信号的抗干扰能力。该方法简单、操作方便易行。通过实验及现场应用证明 。

In this paper, a simple method of anti interference in data collection system is introduced. For the interference between two or more different characteristic data, the data can be collected after being filtered. Thus the useful signals can be transmitted smoothly by restraining the interferential signals. This method is simple in theory and easy in operation. It can be applied in oilfields easily.
