Method of processing seismic signals for reduce the dip effects in the analysis of curvature of the indicators

摘要

Method of processing seismic signals for the analysis of curvature of the indicators. It is of the type consisting of carrying out the following steps: a transmit and receive on the receivers of the waves reflected in the said medium and the recording in the form of seismic traces, b define a succession of n integral indices j between two limits (jmin, jmax) and representative of the curvatures of the indicators of at least one collection of traces, c, calculating a focusing depth time tp for each value of j, to define a series of p integer numbers u, defining a gap (p - 1) deltax, e copy, for each value of j, each trace is identified by its parameters x0 and h, as many times as there are integer numbers u in the interval (p - l) deltax, f applied to each of said traces copied at least one static correction (dt) depending on at least of the parameters d, h and u deltax, g, repeat the steps e and f for all the values of x0 and j.
