abstract = {In view of the characteristics of nuclear magnetic resonance (NMR) logging teaching with strong theory content and abstract and complex principles, this paper designs a reservoir fluid identification simulation experiment of nuclear magnetic resonance (NMR) dual waiting time (TW) logging based on MATLAB GUI. The designed MATLAB GUI interactive interface includes the construction of formation T2 spectrum model, fluid polarization, dual TW echo data forward modeling and echo data processing modules. By entering different parameters in the simulation experiment, the simulated formation T2 spectrum model, long and short TW echo data and processing results can be displayed in real time in the graphical interface, and the actual NMR logging data are processed. The simulation experiment is simple to operate, which can visually display the reservoir fluid identification process and results of NMR dual TW logging to students, enhance students' understanding of the fluid identification method, and improve the teaching effect of NMR logging.}
