天然气水合物矿体的三维地震与海底高频地震联合采集技术——海底地震仪观测系统研究
Three-dimensional Seismic and OBS Joint Acquisition Technology for Gas Hydrate Investigation
【摘要】 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。
【Abstract】 The three-dimensional seismic and OBS joint acquisition technology plays an important role,especially for natural gas hydrate seismic survey research.Study on OBS can provide strong guarantees for gas hydrate investigation.OBS laying on the seabed is the key to joint acquisition.OBS observation system study has an important bearing on OBS data quality.The study could be helpful for designing the best observing systems,which could provide the basis for the joint acquisition of data,reduce acquisition costs and increase operational efficiency.
