Abstract

U sklopu ovog rada provedeno je ukupno 16 mjerenja toplinske vodljivosti stijena na tri lokacije, od kojih se dvije nalaze u istočnom dijelu Dravske depresije. Mjerenja su izvedena metodom iglene sonde (engl. Single Needle Probe), koristeći uređaj Thermal Properties Analyzer. Pet točaka mjerenja je izvedeno unutar lapora, a po jedna točka unutar gnajsa, biokalkarenita, filita i biokalkarenita do biokalkrudita Dobiveni rezultati su uspoređeni s podatcima iz literature te je uočeno da se većina izmjerenih vrijednosti toplinske vodljivosti nalazi unutar prosječnog intervala vrijednosti za određenu vrstu stijene. Poneka odstupanja određenih izmjerenih vrijednosti se vrlo vjerojatno mogu prepisati malo drugačijem mineralnom sastavu stijene za koje su dane vrijednosti u literaturi u odnosu na stijene ispitane u okviru ovoga rada. Osim toga, razlike su vjerojatno utjecane i različitim uvjetima mjerenja. Potrebna su daljnja istraživanja kako bi se vrijednosti korigirale za utjecaje saturacije fluidima koje se očekuju u podzemlju.

Abstract (english)

As part of this work, a total of 16 measurements of thermal conductivity of rocks were carried out at three locations, two of which are located in the eastern part of the Drava Depression. The measurement was performed using the Single Needle Probe method, using the Thermal Properties Analyzer device. Five measurement points were made inside marl, and one point each inside gneiss, biocalcarenite, phyllite and biocalcarenite to biocalcrudite. The obtained results were compared with data from the literature and it was assessed that most of the measured thermal conductivity values are within the average value interval for a certain type of rock. A few deviations of certain measured values can very likely be attributed to the slightly different mineral composition of the rocks for which the values are given in the literature compared to the rocks examined in this work. In addition, the differences are probably due to different influences and measurement conditions. Further research is needed to correct the values for the influence of fluid saturation expected in the subsurface.
