Abstract

Método de exploración sísmica del tipo que consiste en emitir en el medio a explorar, con la ayuda de por lo menos una fuente de emisión de las señales acústicas vibratorias de larga duración en, por lo menos, un punto de emisión, las frecuencias de las señales emitidas que están comprendidas en un espectro de frecuencia deseada, a recibir sobre, por lo menos, un receptor, las ondas reflejadas por los diferentes reflectores del medio a explorar, a efectuar un tratamiento de las señales recibidas para determinar los reflectores detectados formando el espectro complejo de la señal recibida correspondiente a la señal emitida, así como el espectro complejo de una referencia de la señal emitida y dividiendo el espectro complejo de la señal recibida por el espectro complejo de la referencia de la señal emitida, caracterizada porque el espectro de frecuencias está dividido en varias bandas distintas, siendo efectuado el tratamiento sobre las señales recibidas y de referencia correspondientes a cada una de las bandas de frecuencias y en que durante el citado tratamiento se elimina por lo menos una parte exterior de cada uno de los espectros complejos para cada banda de frecuencia considerada.
