摘　　要：双船折射/广角反射地震采集作为获取野外高质量地震数据的一种重要方法,愈来愈受到人们的关注。此方法的优势是用于常规地震难以成像的差记录和无记录区的地震数据采集。介绍了双船折射/广角反射的地震勘探技术,该技术利用折射、广角反射和高速层中的转换波对高速屏蔽层之下的低速层成像原理。通过研究,可以设计合理的观测系统,有针对性地选择目的层进行勘探,为南海北部海域油气资源调查提供技术支持。Undershooting refractive wide-angle reflection seismic acquisition could acquire field high quality seismic data, which is paid more and more attention. The advantage of this approach is used in conventional seismic to imaging of the difference of recorded and unrecorded area seismic data acquisition. The undershooting refractive wide-angle reflection seismic exploration technology was introduced, using of wide-angle reflection and refraction technology, high-speed layer of converted wave in high velocity layer under low velocity imaging principle. Therefore, through research, the rational design of observation system could realize the targeted selection of target layer exploration, for the northern area of the South China Sea oil and gas resources investigation and provide technical support.
