摘　　要：南堡滩海地区由于特殊的地震地质条件,原三维地震采集资料已不能满足现阶段油气勘探的需要。自2002年后,根据富油气凹陷油气成藏规律和该区的整体地质评价,对其进行了整体高精度三维地震采集部署。新一轮采集在科学设计和严格施工的基础上,充分利用先进的采集技术并发挥现有设备条件,如细分面元观测系统、PATCH块束状观测系统、OBC海底电缆等,较好地解决了滩海地区三维地震采集中存在的诸多难题,并获得了高质量的地震资料,为南堡凹陷滩海地区勘探取得重大发现提供了必要基础。Because of the special seismic geologic condition,the original 3D seismic data in Nanpu beach area could not effectively meet its technical needs of petroleum production.Since 2002,on the basis of rich oil sag congregation rules and the integer geologic evaluation,the integer high resolution 3D seismic acquisition system was designed.Based on scientific design and strict construction,advanced acquisition technologies and existing equipment are applied sufficiently,such as flexi-bin geometry,PATCH bind geometry,OBC submarine cable,solving the existing problems of 3D seismic data acquisition in beach area preferably,obtaining high-quality seismic data,and providing a basis for the exploration in Nanpu beach area.
