摘要：A method and device are disclod particularly adapted for ismic prospection in substantially horizontal drains using intermediate frequency acoustic waves for conciliating the range and the power of resolution. In a well is lowered steps-by-steps a transmission-reception asmbly comprising at least one probe associated with a guide block but able to be mechanically uncoupled therefrom, and at least one acoustic wave source associated with a guide block. The source is inrted in a rigid column connecting the probe to the surface control device. A delayed connection system makes it possible to connect the probe and the source electrically to a surface control and recording asmbly. The source compris one or more vibrators transmitting in the 200-2000 Hz band for example or a sparker.
