A streamer for seismic prospection comprising tilt compensation of directional sensors

摘要

A streamer for seismic prospection comprising directional sensors (20), such as geophones or accelerometers, distributed along the streamer, characterized in that said streamer comprises at least two tilt sensors (30, 40) located in remote positions and in locations distant from the directional sensors (20) and means which determined the effective orientation of each directional sensor (20) by interpolating along the streamer the tilt detected by the two tilt sensors (30, 40). The streamer further comprises auxiliary means for determining the orientation of a first wavefield received on a directional sensor (20) and which determine the effective orientation of each directional sensor (20) from the orientation of this first wavefield.
