Abstract

Požeška kotlina predstavlja relativno slabo istražen dio hrvatskog dijela Panonskog bazena. Zbog debelog slijeda kvartarnih naslaga na površini, prve informacije o dubinskoj građi dobivene su na temelju geofizičkih istraživanja u sedamdesetim i osamdesetim godinama 20. stoljeća. U ovom radu, jedini postojeći seizmički podaci su, zajedno s bušotinskim, interpretirani u računalnom programu Schlumberger Petrelu. Dostupni seizmički profili reinterpretirani su te prebačeni u dubinsko mjerilo kako bi se mogle konstruirati karte reprernih horizonata. Na temelju konstruiranih ploha horizonata napravljen je strukturni model istraživanog područja. U konačnici je pomoću metode umjetnih neuronskih mreža u programu Statistica predviđen litološki sastav na trasama seizmičkih profila. Svrha izrade modela je priprema podataka za procjenu ugljikovodičnog potencijala ovog izoliranog dijela podzemlja

Abstract (english)

Požega Valley is relatively poorly e[x]plored area of the Croatian part of the Pannonian Basin. Due to the thick Quarternary deposits on the surface, first detailed insights into the subsurface r[e]lations were made in the 70’ and 80’ of the 20th century. This was after the first geophysical surveys and exploration drilling had been preformed. Re-interpretation of the seismic sections and time to depth conversion have been performed in order for the major horizons surfaces to be constructed. Generated horizon surfaces have been used for the structural modeling of the area. In the end, lithofacies values were predicted by artificial neural network analysis along the section traces using Statistica software. The model has been constructed to enable the evaluation of the hydrocarbon potential of this lateraly-closed area.
