三维地震与海底地震仪(OBS)联合采集技术在野外地震调查中起着举足轻重的作用,特别是对天然气水合物的地震调查方法的研究。其中对海底地震仪(OBS)的研究能够给天然气水合物调查提供有力的保障,OBS在海底的布设是联合采集的关键,对OBS观测系统的研究显得尤为重要,关系到OBS采集的野外资料的总体质量和后期解释。因此,通过研究,可以选择设计最佳的观测系统,为联合采集技术提供基础数据,降低采集费用、提高作业效率。
The combined acquisition technology of 3D seismic and seabed seismograph (OBS) plays an important role in the field seismic survey, especially the research on the seismic survey method of gas hydrate. Among them, the research on the seabed seismograph (OBS) can provide a strong guarantee for the investigation of gas hydrates. The laying of the OBS on the seabed is the key to joint acquisition. The research on the OBS observing system is particularly important, which is related to the field data collected by OBS Overall quality and later interpretation. Therefore, through the research, we can choose to design the best observation system, provide the basic data for the joint acquisition technology, reduce the collection cost and improve the work efficiency.
