摘要：A method includes obtaining, with a plurality of receivers of a logging tool, a setof induction, multi-spacing, multi-frequency measurements of a plurality of nestedcasings. The method also includes inverting, with a processor, the set of measurementsfor magnetic permeability or electrical conductivity. The method further includescalibrating, with the processor, the set of measurements using differences betweenmeasured responses of the logging tool, and simulated responses of the logging toolresulting from inverting the set of measurements for the magnetic permeability orelectrical conductivity of the plurality of nested casings, to determine a calibrated set ofmeasurements. The method also includes inverting, with the processor, the calibrated setof measurements for thickness of individual casings of the plurality of nested casings, todetermine the thickness of the individual casings.
