Abstract
A device for coupling a receiver system with the wall of a well (1) bored in the ground comprises at least one sensor (11;12) sensitive to vibrations, structure (14,15) for applying the system against the wall of said well at the two ends of the system. A surface for supporting the system against the wall, arranged between the applying structure, has a radius of curvature essentially identical to the radius of curvature of a transverse section of the well so that this contact surface (MN) between said system and the wall follows a portion of a cylinder contained within an arc equal to at least 90.degree..
