Abstract :Fluids can be cletennined on samples directly using NMR technique [1 ,2,3]. The aınplitude of the NMR signal is related to the nun1ber of hydrogen protons, the technique can be use d in geophysics to ıneasure the water conteni of rocks and so i ls [ 4,5]. In this study, to identify relaxation tiınes according to porosity values w e used synthetic samples. For the NMR ıneasuren1ents, we used monoınodal glass pearl samples insert ignore into journalissuearticles values(0, 1-0,5-0,8-1 ının); and san d saınples insert ignore into journalissuearticles values(0,35-0,75-1,5 mm); with additional water or petroleun1. According to the relaxation times we measured porosity and compare them with ordinary Iab measurement results. For the results T 1 insert ignore into journalissuearticles values(JNVREC); and T2insert ignore into journalissuearticles values(CPMG); relaxation tin1es are ınuch better suited than T2*insert ignore into journalissuearticles values(FID); for the analysis. All n1easuren1ents were carried out in the departn1ent of Geoscience, Technical University of Berlin in Gennany.
