| 摘 要： | 深水陆坡区水深急剧变化,峡谷纵横,水道复杂,形成了崎岖的海底地形地貌,严重影响到其下伏地层的地震成像,并造成地震剖面上构造形态的畸变.本文利用复杂介质条件下共聚焦分析和CRP分析方法,讨论深水区崎岖海底条件对下伏目的层地震波成像质量的影响,通过对比分析水平海底条件与崎岖海底条件下成像的差别,为深水崎岖海底地区的地震采集设计提出建议.

| Abstract: | There are rapidly-changed water depth,crossed canyons and complicated channels in a deep slope area,resulting in rough seafloor topography,where seismic imaging of underlying stratigraphic intervals is seriously influenced,with distorted structural shape on a seismic section.In this paper,the focal beam analysis and Common-reflection-point(CRP) analysis is applied to the rough seafloor topography from Baiyun deepwater area,providing guidance for designing seismic acquisition in a deep rough seafloor area. |
