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。以南海北部白云深水区崎岖海底地貌为基础,利用高斯射线束正演模拟方法,对深水崎岖海底界面、深水崎岖海底下伏水平界面和浅水崎岖海底下伏水平界面等3个概念模型进行了地震波的激发照明与接收照明的能量分布特征研究,其结果可为深水崎岖海底地区地震采集设计提供指导。

关 键 词:高斯射线束正演模拟  激发照明  接收照明  能量分布  深水崎岖海底

Abstract:There are rapidly-changed water depth,crossed canyons and complicated channels in a deep slope area,resuling in rough seafloor topography,where seismic imaging of underlying stratigraphic intervals is seriously influenced,with distorted structural shape on a seismic section.On a basis of the rough seafloor topography in Baiyun deepwater area,the northern South China Sea,the energy distribution pattern of seismic shot and receiver illumination was researched by the method of Gaussian bean forward modeling fo...
Keywords:Gaussian beam forward modeling  shot illumination  receiver illumination  energy distribution  deep rough seafloor
