Abstract

Ovaj rad obuhvaća izradu potpovršinskog modela Karlovačke uleknine u Savskoj depresiji. Ulazni podatci za modeliranje preuzeti su iz već postojećih strukturnih karata napravljenih 80-ih godina prošloga stoljeća. Izvorne karte izrađene su na osnovi geoloških i geofizičkih podataka, prilikom čega je izdvojeno šest elektrokarotažnih repera i markera koje dijele litostratigrafske jedinice, naziva (Tg, Rs7, Rs5, Z, Rφ i α). Obuhvaćeno područje modeliranja iznosi 1084 km2. Ručno napravljene strukturne karte prebačene su u računalni program Arc GIS 10.1, nakon čega je modeliranje vršeno u programu PetrelTM 2014. Model pokazuje oblik geološke strukture, prikaz plohe EK markera i repera, pružanje glavnih i sporednih rasjeda. Napravljene su i karte pogreške koje prikazuju odstupanje modela od izvornih karata. Izračunata je greška između izvornih karata i modela, te ona iznosi 4,682 %. Prednost modeliranja u odnosu na ručnu interpolaciju je prikaz trodimenzionalnog oblika podzemlja, koji daju jasniju sliku za daljnju znanstvenu obradu.

Abstract: The goal of this Thesis was to get digitalised the subsurface model of the Karlovac subdepression, part of the Sava depression. Input data for modelling were previously constructed structural maps made in 80’s which were based on geological and geophysical data from that time. Six maps of E-log-defined contacts and E-log markers (Tg, Rs7, Rs5, Z, Rφ and α) existed. Size of the digitalisation area is 1084 km2. The first step was geolocation and feature digitalization of those maps in Arc GIS 10.1 and afterwards modelling in the PetrelTM 2014. The result was a model which represents geological structures, E-log horizons, surfaces as well as fault planes. In the end the percentage of error was calculated between handmade and digitalised maps, which is 4.682%. The advantage of digitalised model in comparison with previous interpolation is getting a 3D data of the subsurface, which is necessary for further modern exploration.
