METHOD FOR PROCESSING SEISMIC SIGNALS TO REDUCE DIPPING EFFECTS IN THE ANALYSIS OF BENDING INDICATORS

摘要

P Method of processing seismic signals for the analysis of curvature of indicatrixes. It is of the type consisting in carrying out the following steps: a transmitting and receiving on receivers waves reflected in said medium and recording them in the form of seismic traces, b defining a series of N integer indices j between two limits (Jmin, Jmax ) and representative of the curvatures of the indicators of at least one collection of predetermined traces, c calculate a time of focusing depth tp for each value of j, d define a series of P whole numbers u determining an interval (P-1 ) DELTAx, e copy, for each value of j, each trace identified by its parameters x0 and h, as many times as there are whole numbers u in the interval (Pl) DELTAx, f apply to each of said copied traces at least one static correction (dt) depending at least on parameters j, h and u DELTAx, g repeat steps e and f for all the values of x0 and j. /P
