Features of spectral analysis of nuclear magnetic resonance signal for express-control of hydrocarbon media

The article substantiates the need to study the structure of the nuclear magnetic resonance signal recorded using the modulation technique. For the stationary and current state, the characteristic features of recording a nuclear magnetic resonance (NMR) signal using the modulation method were determined. The influence of the properties of the medium on the features of recording the NMR signal has been determined. A new method is proposed for determining the contributions of absorption and dispersion signals to the recorded NMR signal. The features of the use of spectral analysis in the study of the NMR signal from hydrocarbon media have been determined.
