| 摘 要： | 海洋宽频带地震采集和处理技术在近年取得了长足进展。在激发和接收阶段，为了有效降低鬼波对地震波中低频和高频段有效波的影响，拓宽地震数据频带，人们开发出上下源或多层震源延迟激发技术和上下缆、变深度拖缆、双检电缆等采集技术，这些新技术的应用，提高了地震原始数据的分辨率和信噪比，为提高地震数据的成像与反演处理精度奠定了良好的基础。

| Abstract: | In recent years, much progress of broadband seismic data acquisition and processing has been made in marine exploration. In order to widen seismic bandwidth and suppress ghost on low and high frequency seismic data, new approaches are developed. For seismic source, over/under air-gun arrays and multi-depth sources are introduced. And for seismic recording, over/under streamers, variable-depth streamers, and dual-sensor streamers have increasingly been used. All of these new approaches can improve seismic data resolution and SNR, and furthermore lay a solid foundation for improving seismic imaging and inversion. |
