Abstract

Istočni dio Dravske depresije, kao i istraživano šire područje polja Crnac, točnije sinklinale zapadno od polja Crnac, je već poznato po akumulacijama ugljikovodika, stoga je i naftno – geološki dobro istraženo. Kako bi se detaljnije istražilo, napravljen je geološki model te potom načinjena bazenska analiza na temelju koje je napravljena procjena generiranih ugljikovodika. Uz već postojeću literaturu i dobivene ulazne seizmičke i bušotinske podatke, napravljen je jednostavni 3D model u... More softveru Petrel 2020. Nakon definiranja graničnih uvjeta okoliša taloženja i toplinskog toka načinjeni su 1D i 3D modeli u softveru Petromod 2020.1, gdje je pokrenuta i dinamička simulacija. Rezultati dinamičkog modeliranja ukazuju nam na povoljnu dubinu matičnih stijena te ulazak u naftni prozor. Akumulacije ugljikovodika predviđene su u brečokonglomeratima Vukovarske formacije u manjim akumulacijama, no većina ugljikovodika je migrirala lateralno što se podudara s postojećim akumulacijama u okolici. Ovo modeliranje i dobiveni rezultati mogu poslužiti za daljnja istraživanja uvjeta generiranja i nakupljanja ugljikovodika u širem području. Less

Abstract (english)

The eastern part of the Drava Depression, as well as wider area of the Crnac field, more precisely the synclines west of the Crnac field, is already proven hydrocarbon bearing area; therefore, it has been well explored. In order to make more detail research, a geological model was made as well as a basin analysis, based on which an estimate of the generated hydrocarbons was made. In addition to the existing literature and obtained seismic and well data, a simple 3D model in Petrel 2020... More software was created. After defining the boundary conditions of the deposition and heat flow environment, 1D and 3D models were made in Petromod 2020.1 software, where a dynamic simulation was started. The results of dynamic modelling indicate a favourable depth of the source rocks and the entry into the oil window. Accumulations of liquid hydrocarbons are predicted in the breccia conglomerates of the Vukovar Formation in smaller accumulations, but most hydrocarbons migrated laterally, which coincides with the existing accumulations nearby. This modelling and the obtained results can be used for further research of hydrocarbon generation and accumulation in broader area. Less
