TWO DIMENSIONAL PROCESSING FOR MULTIPLE NESTED STRING VARIABLE THICKNESS PROFILE EVALUATION USING MULTIFREQUENCY NON-COLLOCATED INDUCTION MEASUREMENTS

原文（中国語）

Systems and methods to determine a thickness profile of nested metallic pipes can include processing long sections (windows) of induction multi spacing and multi frequency noncollocated sensor measurements (attenuation and phase). The systems and methods also include using an inversion based process to deconvolve the tool transfer function from the surrounding pipe structure and its anomalies by running an axisymmetric finite element method (FEM modeling solver with a model in an inversion loop.
