【摘要】 基于AVO和地震波吸收衰减的地震反射振幅理论模拟分析,在获得了南黄海盆地主要反射界面的地震反射振幅与偏移距关系的基础上,分析了常规地震勘探面临的主要困难,提出了在采用大容量、长排列地震勘探的同时,应适时采用立体气枪震源、上下缆和双检地震等先进的地震勘探技术,同时开展大地电磁、OBS等勘探技术,以获得深部地层的有效地球物理信息。更多还原

【Abstract】 According to AVO and the theory of seismic reflection amplitude absorption and attenuation,after modeling and analysis,we have gained the relation between amplitude and offset of main reflection interfaces in the South Yellow Sea.However,problems and difficulties remain with the traditional seismic exploration after all these efforts.We suggest making use of seismic exploration technology with large source capability and long receive array.Some advanced technology such as cubic air-gun source,over/under streamer and dual-sensor should be taken into account.In order to get effective geophysical information on deep sediments,magnetotelluric method and OBS technology should also be considered.更多还原
