BOTTOM-REFERENCED SEISMIC CABLE WITH VERTICAL HYDROPHONE ARRAYS |
摘要 |
A bottom-referenced cable system for marine seismic exploration includes a bottom-referenced cable (41) adapted to be deployed on the water bottom (29). The cable (41) has multiple take-outs (43) at intervals thereof, and multiple vertical pressure sensor arrays (45) each connected to the cable (41) at one of the take-outs (43). Each vertical pressure sensor array (45) has at least a lower pressure sensor (49L) and an upper pressure sensor (49U) disposed in vertical spaced relation, and a float (47) for maintaining its vertical orientation.
