Abstract：With dual-vessel towing streamers,we can deploy flexible seismic acquisition geometry.This acquisition geometry has various advantages such as larger offset,higher common mid-point (CMP) folds,dual-azimuth illumination (split spread),etc.At the same time,the large volume broadband source can be used in the seismic acquisition,and variable depth towed-streamers will help de-ghosting during the data processing.All these will greatly improve deep target imaging.So we have carried out a dual vessel seismic broadband acquisition experiment.Final seismic sections show better imaging and higher resolution on both shallow layers and deep targets.This confirms the effectiveness of the proposed acquisition approach and it is worth to use in complex subsurface areas.
