摘　　要：地震勘探采集系统作为一个大型的电子设备,在地震勘探数据采集过程中,经常会受到外界不可见的电磁干扰,由于检波器接收到的中深层反射信号较弱,因而这些干扰对原始的地震数据影响很大,会造成原始数据失真,致使采集质量下降。本文从地震勘探数据采集系统受电磁干扰的途径进行分析,提供了一些相应的解决方法。As a large scale of electronic equipment, the seismic data acquisition system often suffers from the external invisible electro-magnetic interference during data acquisition, which affected raw seismic data because of weaker reflection signal received by geophones, that resulted in distortion of original data and poor quality of data. The paper analyzed the way that seismic data acquisition system suffers from electronic-magnetic interference and provided some corresponding solved methods.
