CORRECTION FOR GAIN VARIATION DUE TO FAST CHANGING NMR SENSOR GAIN
摘要
An apparatus for performing nuclear magnetic resonance (NMR) measurements of a material of interest includes an NMR tool and a processor. The NMR tool includes a transmitter antenna; a transmitter coupled to the transmitter antenna; and a receiver antenna configured to receive NMR signals in response to transmitted pulses of electromagnetic energy transmitted by the transmitter antenna. The NMR signals include at least a first signal and a second signal of a phase-alternated group of signals. The processor is configured to receive the NMR signals; receive a first system gain related to the first signal and a second system gain related to the second signal, each system gain being related to a system comprising the NMR tool and the material of interest; and calibrate the NMR signals using the first system gain and the second system gain.
