Summary:The present invention discloses a method for separating oil-water two-phase NMR signals by using dynamic nuclear polarization, specifically comprising: adding free radicals into an oil and water-containing sample to be tested to enhance the water phase or oil phase NMR signals, then performing nuclear magnetic resonance analysis detection of enhanced dynamic nuclear polarization, to obtain the water phase or oil phase NMR signals. The method is simple and easy to operate, has a short test time, and can efficiently separate the oil-water two-phase NMR signals. La présente invention concerne un procédé de séparation de signaux RMN à deux phases huileuse-aqueuse à l'aide d'une polarisation nucléaire dynamique, qui comprend plus particulièrement : l'ajout de radicaux libres dans un échantillon pétrolifère-aquifère devant être analysé afin d'améliorer les signaux RMN en phase aqueuse ou en phase huileuse, puis l'exécution d'une détection d'analyse par résonance magnétique nucléaire de polarisation nucléaire dynami
