摘　　要：为满足国家908专项DW10区块的调查要求,在北部湾海域进行了24道高分辨多道地震探测,此多道地震系统主要由电火花震源、道间距为6.25 m的24道电缆以及采集主机组成,通过系统的合理配置以及在野外作业过程中合理设计采集参数,获得了高分辨的地震数据,最大穿透深度可达1 000 m以上,分辨率可达3.5 m,实践证明,此次使用的24道多道地震系统的探测是一种适用于浅部地层高分辨探测的调查技术手段。High resolution seismic surveying was carried out in the Beibuwan Gulf area by 24 channel seismic system which consists of sparker source,6.25 m group intervals digital streamer and recorder system.By configuring the system reasonably as well as setting collection parameters reasonably in the process of field surveying,high-resolution seismic data with more than 1 000 m penetration of strata and 3.5 m resolution is acquired.The results show that 24 channel high-resolution seismic system may be an effective method for high-resolution exploration of the shallow strata.
