深海声道对波场传播的影响
Keywords: 深海声道,走时,射线路径,振幅
Abstract:
？深海声道是存在于一定水深中的声波波导，造成海水速度呈层状结构分布，引起波场传播中射线路径、走时以及振幅的变化，进而影响偏移成像的质量，其影响程度随着传播距离的增加而变化。为了定量研究海水速度沿垂直方向的变化对地震偏移剖面的影响程度，本文建立了深海声道模型，并在深海声道模型和海水速度取常数模型上分别应用波前构建法计算地震波走时、射线路径以及振幅，通过对比两种模型的计算结果和偏移成像结果，了解深海声道对波场传播的影响，得出以下认识：深海声道对射线路径造成的影响在海洋地震资料处理时是不可忽略的；深海声道对地震波走时的影响可以忽略；深海声道对振幅的影响非常强烈。
