Wyznaczanie przepuszczalności skał na podstawie pomiarów porozymetrycznych i magnetycznego rezonansu jądrowego

Abstract

Permeability, the most important reservoir parameter can be directly measured only on rock samples. It can be also determined on the basis of various statistical relationships between petrophysical parameters. We tested usefulness of Swanson parameter from the mercury porosimetry and relaxation time T2 from the NMR to find adequate formulas to improve permeability determination. We used the Devonian carbonates and Carboniferous mudstones and the Rotliegend sandstones.
