南海北部海域油气资源调查技术及其应用研究——拖缆及海底地震仪联合勘探观测系统研究

Study on the Application of Oil-Gas Exploration Technologies in the North of the South China Sea: Towline and OBS Joint Seismic Survey

拖缆与海底地震仪联合勘探技术在野外地震调查中起着举足轻重的作用,特别是对油气资源的地震调查方法的研究。其中对海底地震仪(OBS)的研究能够给深水油气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,为联合勘探技术提供基础数据,降低采集费用、提高作业效率。

The towline and three-dimensional OBS joint acquisition technology plays an important role in field seismic survey, especially for the research on natural gas hydrate seismic survey methods. Study on the Ocean Bottom Seismograph（OBS） can provide solid support for deep-water oil and gas exploration. The layout of OBS on the seabed is the key of joint acquisition. The OBS observation system has a particularly important bearing on the overall quality and later interpretation of the OBS data collected in the field. Through research, the optimal observing systems can be chosen to provide basic data for the joint acquisition technology, which can also reduce the acquisition costs and improve the operational efficiency.
