Title (EN) SEISMIC DEVICE
(FR) DISPOSITIF D'EXPLORATION SISMIQUE
Abstract:
(EN) Device comprising instruments for the collecting and recording of signals in seismic exploration of the formation off-shore. The intermediate main portion (1) is approximately cylindrically shaped and is connected to a pointed end (2) via a vibration absorbing spacer (6). The other end of the intermediate main part is connected to a top part designed for insertion/pulling and other ways of handling the device, where the pointed end at least comprises geophones and a hydrophone is placed in or near the upper end of the device, and the other instruments of the device are situated in the middle main portion.
(FR) Dispositif comprenant des instruments pour capter et enregistrer les signaux lors de l'exploration sismique du substratum de haute mer. La partie principale intermédiaire (1), quasiment cylindrique, est reliée à une extrémité effilée (2) par un amortisseur de vibrations (6). A l'autre extrémité, elle est reliée à une partie supérieure conçue pour permettre de manipuler ce dispositif, par exemple pour l'insérer ou le retirer. L'extrémité effilée abrite des géophones. Un hydrophone est placé dans ou à proximité de la partie supérieure du dispositif, dont les autres instruments se trouvent dans la partie centrale principale.
