Title
(EN) REMOTE-FIELD EDDY CURRENT CHARACTERIZATION OF PIPES
(FR) CARACTÉRISATION DE TUYAUX À COURANTS DE FOUCAULT CHAMP LOINTAIN
Abstract
(EN)
Described are various approaches for estimating the total thickness of a set of pipes from the phase of the mutual impedance between transmitter and receiver measured with an eddy-current logging tool disposed interior to the pipes, in conjunction with a simulated functional relationship between the phase and the total thickness.
(FR)
On décrit diverses approches pour estimer l'épaisseur totale d'un ensemble de tuyaux à partir de la phase de l'impédance mutuelle entre l'émetteur et le récepteur, mesurée avec un outil de diagraphie à courants de Foucault disposé à l'intérieur des tuyaux, conjointement à une relation fonctionnelle simulée entre la phase et l'épaisseur totale.
