海底电缆地震采集技术是近几年才引入我国的最新物探采集技术, 它采纳了多项当前最新科技成果, 其施工方法也与施缆及遥测仪采集技术有很大的不同。针对这些不同点, 本文从二维和三维采集方法、双检波器及声波二次定位系统的应用出发, 全面地论述了海底电缆地震采集技术的优势。

The ocean bay cable (O. B. C.) seismic acquisition technique was introduced to our country inrecent years as the latest geophysical acquisition technique. lt adopts severa1 state-of-the-artscientific and technological achievements. lts construction rnethod is also different from thestreamer and telemetry acquisition techniques. In view of the difference, starting from theapplications of 2D and 3D acquisition method, dual receiver, and acoustic secondary positioningsystem we comprehensively expound the advantages of the O. B. C. seismic acquisition technique.
