Abstract

U okviru ovog diplomskog rada digitalizirani su i obrađeni podatci iz prijašnjih strukturnih karata istočnog dijela
Dravske depresije, dobivenih na temelju dotadašnjih dubinsko – geoloških i geofizičkih istraživanja, bušenja,
površinskih geoloških istraživanja i njihove interpretacije. Strukturne karte napravljene su po plohama pet
elektrokarotažnih repera i markera koji dijele litostratigrafske jedinice, a to su: A, B, G, H, Tg. Područje se
nalazi u istočnom dijelu Hrvatske, najvećim dijelom u Osječko - baranjskoj županiji. Digitalizacija i obrada
podataka napravljena je pomoću računalnih programa ArcMap 10.1 te Schlumberger PetrelTM 2014. Prikazan je
procesizradbe geomodela te pogreške koje mogu nastati prilikom njegove4 izradbe. Model jasno pokazuje
odnose između glavnih i sporednih rasjeda, geološke strukture, strukturne zamke te utjecaj rasjeda na
oblikovanje površina u prostoru. Napravljeni trodimenzionalni prikazi strukturnih odnosa, razvoja geoloških
struktura po različitim plohama EK – markera i repera te pomaci terena uzorkovani rasjedima uvelike obogaćuju
sliku i razumijevanje dijela podzemlja zapadnog dijela istočno Dravske depresije. Računanjem prosječne
vrijednosti odstupanja modela od ručno izrađenih strukturnih karata koja iznosi 0,787% utvrđena je velika
točnost i preciznost same obrade podataka.

Abstract: The main goal was the accurate digitalization and subsurface modelling of the paper-based geological maps. The
research area is located in Croatian part of Pannonian Basin System, Drava Depression. Data input for the
structural analysis were from structural maps which were previously made in the 1980’. Set included four
structural maps based on regional E-log markers and one map of pre-Neogene top. All were digitalized in
program ArcGIS. Structural contours and 43 faults were exported into Petrel software where they were further
processed and regrouped. From such digitalized and processed data the digital geological model (geomodel) was
made using fault framework modelling process. The study concerned the advantages and errors that occur during
creation of such geomodel. It clearly displays relations between major and minor faults and fault slips,
geological structures and structural traps in 3D. Another advantage is multicolored presentation of depths and
faults, which enables easier recognition of geological structures and potential traps for hydrocarbons. Errors and
issues can occur during digitalization of contour lines, selection of the appropriate algorithm and those ones that
arise when model is created.
