Abstract

Analiziran je prostor Bjelovarske subdepresije. Ulazni podatci bile su vrijednosti geokemijskih varijabli, vitrinitne refleksije (Ro) i vremensko-temperaturnog indeksa (TTI) za bušotine Čep (polje), Pav-1, Gr (polje), Ha-7, Le-4, Rov-1, NG-1, VC-1, Vis-1 i Ulj-1 te njihove Gauss- Krügerove koordinate. Zbog nedostatka pet podataka vrijednosti TTI-ja i tri vrijednosti Ro-a, određena je termička zrelost stijena EASY%Ro metodom. Pomoću nomograma se jednostav- nom konverzijom odredila nepoznata varijabla iz para Ro-TTI. Kartirano je metodom inverzne udaljenosti (IDW) pomoću programskog paketa Surfer 8.0TM. Metoda inverzne udaljenosti primijenjena je zbog svoje jednostavnosti u pripremi i brzini u proračunu, ali i dobivenog izlaza koji se može jednostavno i smisleno geološki interpretirati. Metoda inverzne udaljenosti (IDW) je uobičajena metoda interpolacije karata za male uzorke (manje od dvadeset podataka) u Hrvatskom panonskom bazenskom sustavu. Nanovo načinjene digitalne karte poslužile su za doradu postojeće karte migracijskih putova ugljikovodika.

Abstract (english)

The area of Bjelovar subdepression was analyzed at the regional level (the entire subdepression). Input data were values of geochemical variables, vitrinite reflection (Ro) and Time Temperature Index of Maturity (TTI) for wells Čep (field), Pav-1, Gr (field), Ha-7, Le-4, Rov-1, NG-1, VC - 1, Vis-1 and Ulj-1 and their Gauss-Krüger coordinates. Due to the lack of five TTI value data and three Ro values, the thermal maturity of the rocks was determined by the EASY%Ro method. Using a nomogram, an unknown variable from the Ro-TTI pair was determined by simple conversion. Mapping was carried out by Inverse Distance Weighting method using the Surfer 8.0TM software package. The Inverse Distance Weighting method was applied due to its simplicity in preparation and speed in the calculation, but also the obtained output, which is relatively clear. Furthermore, within the subdepression, the Inverse Distance Weighting method (IDW) has been identified as the most appropriate interpolation method because it is a common method, of interpolating maps for small samples (less than twenty pieces of data) in CPPB. The newly created digital maps served as a new map of hydrocarbon migration pathways.
