摘　　要：当前的海上地震勘探朝着三维多缆、更多地震接收道、更高分辨力方向发展。用于地震勘探电缆接收道的数字检波器,其性能已有了很大提升。以法国Sercel公司生产的"海豹"充油电缆为例,简要介绍接收道基本结构和检波器原理,并对其在野外作业中的性能进行了分析和评价,以指导电缆的使用和检修。In recent time, three dimensional multiple cables, more channels and higher resolution on marine seismic exploration have been developed . The performance of the digital detector used in cable receive channel has been improved obviously. Based on ＂seal＂ oil-filled cable producted on Sercel company in France, we briefly introduced the basic structure of cable receive channel and evaluate its performance through field practice. These results will help us to direct the cable usage and troubleshooting.
