Title (EN) HIGH-RESOLUTION REMOTE-FIELD EDDY CURRENT CHARACTERIZATION OF PIPES
(FR) CARACTÉRISATION DE TUYAU SUR LA BASE DE COURANTS DE FOUCAULT CHAMP LOINTAIN À HAUTE RÉSOLUTION
Abstract:
(EN) In pipe characterization based on the remote-field eddy current effect, the resolution with which the total pipe thickness can be determined from measurements of the phase of the mutual impedance between the transmitter and the receiver of an eddy-current logging tool can be improved with a deconvolution approach utilizing the simulated or measured impulse response of a small pipe defect.
(FR) Dans la caractérisation de tuyau sur la base de l'effet de courants de Foucault champ lointain, la résolution selon laquelle l'épaisseur totale du tuyau peut être déterminée à partir de mesures de la phase de l'impédance mutuelle entre l'émetteur et le récepteur d'un outil de diagraphie à courants de Foucault peut être améliorée par une approche de déconvolution utilisant la réponse impulsionnelle simulée ou mesurée d'un petit défaut de tuyau.
