W artykule zaprezentowano wyniki badań laboratoryjnych przeprowadzonych na rdzeniach wiertniczych, a uzyskane na podstawie nowoczesnych metod badawczych: jądrowego rezonansu magnetycznego (NMR) i mikrotomografii rentgenowskiej (micro-CT). Wykonano analizę nasycenia przestrzeni porowej skał na podstawie kształtu i rozkładu krzywej czasu relaksacji poprzecznej T2. Określono zależność pomiędzy rozkładem czasów T2 a charakterem nasycenia przestrzeni porowej utworów eolicznych i fluwialnych. Otrzymane wyniki skorelowano z wynikami badań micro-CT próbek (ich charakterystyką i obrazem 3D przestrzeni porowej). Przedstawione opracowanie pokazuje ogromny potencjał badawczy obu wymienionych metod w analizie cech petrofizycznych i właściwości zbiornikowych skał.

In this paper results of rotliegend sandstones samples laboratory tests were presented. Samples were in the form of drilling cores and came from Fore Sudetian Monocline. The results were obtained with the use of modern research methods – X-ray computed microtomography (micro-CT) and nuclear magnetic resonance (NMR). The pore space saturation analysis were performed on the basis of transverse relaxation time (T2) curve shape. The relation between T2 time distribution and pore space saturation's nature in fluvial and eolian samples was determined. Results obtained with the use of NMR method were correlated with micro-CT results. There was found that the nature of the pore network has an impact on pores saturation of free, capillary and non-reducible water. Both applied in this research methods are complementary and together they provide a good research workshop for rocks petrophysical analysis and reservoir properties analysis.
