| 摘要 |
The invention relates to a method of subsoil seismic prospection, of the type in which a seismic wave is emitted at a specified point of the surface of the ground or near the surface of the sea, and the waves reflected by the interfaces between the underlying geological formations are recorded as a function of time with the aid of receivers arranged at a plurality of locations on the surface of the ground or near the surface of the sea, the data recorded by the said sensors are processed with the aid of a mathematical program based on a simplified model of wave propagation and a graphical representation of the geological formations is computed from the data thus processed. According to the invention, prior to processing the recorded data, the amplitudes of these data are corrected so that they correspond to those of waves which would have propagated in accordance with the said simplified model of propagation. <IMAGE> |
