发明名称 METHODE DE TRAITEMENT DE SIGNAUX SISMIQUES POUR REDUIRE LES EFFETS DE PENDAGE DANS L'ANALYSE DE COURBURES D'INDICATRICES
摘要 A method of processing seismic signals for the analysis of moveout is presented in which waves are transmitted in a medium, reflected, received by receivers and recorded in the form of seismic traces. A string of N integers is defined having indices j lying between two limits (jmin, jmax) and representative of the moveouts of at least one predetermined gather of traces. A focus depth time tp for each value of j is calculated. A string of P integer numbers u is defined which determines an interval (P-1) DELTA X. For each value of j, each trace identified by its parameters X0 and h is copied as many times as there are integer numbers u in the interval (P-1) DELTA X. At least one static correction (dt) is applied to each of the copied traces, dependent at least on the parameters j, h and u DELTA X. Copying and static correction are repeated for all the values of X0 and of j.
