地震照明分析技术在深海地震数据采集设计中的应用

摘要
中国南海北部陆缘深水海域是形成大型油气区的有利区域。但由于该区水深急剧变化,峡谷纵横,构成了海底崎岖的地形地貌带,给该区的油气勘探带来了困难。本文利用高斯射线束地震波正演模拟方法,研究了南海白云凹陷深水崎岖海底区地震波对地下目的层的激发照明以及检波器接收照明能量的分布特征。针对不同接收缆数、不同排列长度及不同激发方向对海底崎岖界面和深部目的层的激发与接收照明能量的模拟分析,初步认识崎岖海底和下伏目的层地震波能量的分布特征,以及不同观测系统参数对地震采集能量的影响程度,为南海崎岖深海区地震采集参数设计提供了依据。
The deep water area in the northern continental shelf of South China Sea is the important prospect region for oil and gas.However,it is difficult for oil and gas exploration due to rough seafloor such as sharply variation of water depth,crossing canyons,and complicated channels.Using the Gauss Ray Beam forward modeling,we analyze seismic illumination energy distributions to subsurface targets and shooting illumination and receiving illumination in Baiyun Sag of South China Sea which has typical deepwater rough seafloor features.According to shooting illumination and receiving illumination on the rough seafloor and subsurface targets with different number of streamers and different lengths of streamers,and different sailing direction,we find the distribution character of seismic wave energy on the rough seafloor and underlying formation,and the impact of different geometry parameters on reflected seismic energy.It is well instructional worth for seismic survey design of deepwater rough seafloor area in South China Sea.
