A method for sea mixtures of investigations it should be.

摘要

The invention relates to a process for marine seismic prospection, of the type in which it emits a seismic waves in a determined point close to the surface of the water and is recorded as a function of time, the waves reflected by the interfaces between geological formations in the - ground, with the aid of receivers disposed in a plurality of points close to the surface of the water, with the aid of means of a known type, using the wave equation a mathematical model of multiple signals and of the peg leg, it is subtracted from the data recorded by each of said sensors, the data calculated with the aid of mathematical model m (t, x) in order to obtain corrected data and it is established with the aid of these data corrected a graphic representation of the geological formations in the ground in which is propagated the seismic waves. & br / the invention proposes a mathematical processing of data making it possible to eliminate the multiple signals and the peg leg.
