The invention concerns a device for receiving seismic waves comprising a hydrophone and/or a geophone and a method for coupling them with a solid environment such as an underground zone. The device comprises at least a hydrophone (2) immersed in a flexible-wall housing (7) filled with liquid (8) which is closed at one end with a sealing plug (9) provided with a sealed duct for a cable (10) connecting the hydrophone with signal acquisition means (E). The housing is arranged in a cavity (6) and closely coupled with the environment (5) substantially by its entire surface, preferably with a material capable of setting such as cement. A geophone can be provided in the same coupling material proximate to the housing (7) containing the hydrophone (2). The invention is useful for prospecting operations or seismic monitoring of an underground formation in particular for discriminating ascending and descending seismic waves.
Dispositif de réception d'ondes sismiques comprenant un hydrophone et/ou un géophone et une méthode pour le(s) coupler avec un milieu solide tel que le sous-sol. Le dispositif comprend au moins un hydrophone (2) immergé dans une enveloppe close à paroi souple (7) remplie de liquide (8) qui est fermée à une extrémité par un bouchon étanche (9) pourvu d'une traversée étanche pour un câble (10) de liaison de l'hydrophone avec un moyen d'acquisition de signaux (E). L'enveloppe est disposée dans une cavité (6) et couplée étroitement avec le milieu (5) sensiblement par toute sa surface, de préférence par un matériau durcissable tel que du ciment. Un géophone peut être disposé dans le même matériau de couplage au voisinage de l'enveloppe (7) contenant l'hydrophone (2). Application pour des opérations de prospection ou surveillance sismique d'une formation souterraine notamment pour discriminer les ondes sismiques montantes et descendantes.
