【摘要】 当前的海上地震勘探正朝着三维多缆、更多地震接收道(多通道)、更高分辨率的方向发展。其中,用于地震勘探电缆接收道的数字检波器,其性能和关键技术都有很大的改进和提升。本文以法国Sercel公司生产的"海豹"充油电缆为例,简要介绍了该装置的接收道基本结构和检波器原理,并通过野外作业对其性能进行了分析和评价,从而为海上地震勘探工程中电缆的使用和检修提供参考。更多还原

【Abstract】 Ocean seismic exploration has the tendency to develop three-dimensional multiple cables,more channels and higher resolution in recent Shanghai.The performances and key technologies of the digital sensors used in array’s channel have been improved obviously.Based on SEAL fluid-filled streamer produced on Sercel Company in France,this paper briefly introduces the basic structure of cable channel,and evaluates its performance though field practice,which provides references for cable usage and maintenance on ocean seismic exploration.更多还原
