Abstract: With seismic exploration technology improved, the high-density seismic exploration technology characterized in high space sampling rate has made a great progress. To explore offshore application of this high-density and high-resolution 3D seismic acquisition technology, transverse bird technology was used for the first time at home for seismic data acquisition in PL zone of Bohai Sea, reducing bin size of data and optimizing parameters of seismic source and cable. Meanwhile, based on high-resolution processing, the data results were significantly improved in terms of transverse and vertical resolution, reflecting more abundant geological information, helping understand the fault system and adding exploration targets for selection
