A low-power automated measurement system for pulsed eddy current based inspection of oil-well casing
This paper presents a design of a multichannel measurement system for nondestructive inspection of oil-well casing's mechanical properties (i.e. tube wall thickness and inner diameter), employing pulsed eddy current (PEC) technique. A specific feature of the system is its operation in high-temperature environment (typically up to 175°C), which requires simple and robust circuits, low part-count probe design, low power consumption and proper automated measurement algorithms to ensure reliable operation. Based on our previous work on PEC method, we propose an inspection tool, consisted of a simple, low-length three-coil probe, switch-mode power conditioning and transmitter excitation unit, and a low-power data acquisition and telemetry circuit. Preliminary results of our high-temperature functional tests confirm reliable operation of the inspection tool and provide additional verification of the previously proposed PEC methodology for measurements in harsh environments.
