Method of processing seismic signals for the analysis of moveout

摘要

It is of the type consisting in performing the following steps: a - transmitting and receiving, on receivers, waves reflected in the said medium and recording them in the form of seismic traces, b - defining a string of N integer indices j lying between two limits (j min , j max ) and representative of the moveouts of at least one predetermined gather of traces, c - calculating a focus depth time tp for each value of j, d - defining a string of P integer numbers u determining an interval (P-1)#x, e - copying, for each value of j, each trace identified by its parameters x 0 and h, as many times as there are integer numbers u in the interval (P-1)#x, h being the offset and x 0 the midpoint of each trace, f - applying at least one static correction (dt) to each of the said copied traces, dependent at least on the parameters j, h and u #x, g - recommencing steps e and f for all the values of x 0 and of j.
