Abstract: 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.

Key words: high resolution 3D seismic exploration, seismic geologic condition, geometry, OBC submarine cable, integer design
