Abstract

U okviru ovog rada provedeni su postupci digitalizacije i modeliranja strukturno-tektonskih odnosa zapadnog dijela Savske depresije. Područje modeliranja najvećim dijelom zahvaća područje Zagrebačke županije te obuhvaća površinu od 758,765 km². Strukturne karte, konstruirane po plohama šest elektrokarotažnih EK-repera (Tg) i EK-markera (Rs7,Rs5, Z', Rφ i α'), poslužile su kao temeljni podaci za izradbu ovog rada. Potpovršinske strukturne karte načinjene su prema podacima dobivenim iz geološkog kartiranja i geomorfologije terena, gravimetrijskih i seižmičkih mjerenja te iz bušenja. Strukturne karte su prevedene u digitalni oblik u računalnom programu ArcMap 10.1 te su iste poslužile kao ulazni podaci za kreiranje potpovršinskog modela po plohama svih šest strukturnih horizonata u programu PetrelTM 2013. Potpovršinski model prikazuje blokovitu tektonsku građu područja modeliranja te rasjednute strukture koje predstavljaju hrvatska naftnoplinska polja Dugo Selo, Lupoglav, Ježevo, Kloštar, Ivanić i Šumečani. Malo statističko odstupanje modela od ručno načinjenih karata s iznosom vrijednosti prosječnog odstupanja od 0,6512% upućuje na veliku točnost izradbe geološkog modela prema ručno izrađenim strukturnim kartama. Trodimenzionalni prikaz utjecaja rasjeda, geoloških struktura i strukturnih zamki omogućava prostornu percepciju i razumijevanje podzemlja sjeverozapadnog dijela Savske depresije. Takvi geološki modeli mogu poslužiti za stvaranje složenijih modela te za definiranje i utvrđivanje novih potencijalnih ležišta.

Abstract: The aim of the Thesis was accurate digitalization and geomodelling of structural relationships of subsurface at western part of Sava Depression. Area of modelling encompasses 758.765 square kilometers and is located in central Croatia (Zagreb County). Subsurface structural maps, hand interpolated along six planes of E-logs top (Rs7, Rs5, Z', Rφ and α') and one pre-Neogene top (Tg) were digitalized. Gravimetry, seismic and well data were used for creation of structural maps in 1980. It considered the geomorphology and data obtained by geological mapping of the area. Structural maps were transferred into digital format in a computer program ArcMap 10.1 and were used as input data for creation of a subsurface model along six planes of horizons in the program PetrelTM 2013. Subsurface model shows the radial tectonic structure of the modelling area and impact of the faults on structures which represents oil and gas fields Dugo Selo, Lupoglav, Ježevo, Kloštar, Ivanić and Šumečani. Small statistical error between subsurface model and hand-made maps of 0.6512% indicates accuracy of geomodel. Three-dimensional displays impact of faults on the terrain, geological structures and structural traps enable spatial perception and understanding of geological structures of the western part of the Sava depression. These subsurface models can be used for creation of complex models and for defining and identifying new potential deposits of certain structures and the future development of hydrocarbon reservoirs.
