Abstract

Istraživanje provedeno u ovome radu predstavlja početak istraživanja pješčenjaka Okoli za korištenje u geoenergetske svrhe. U okviru ovog diplomskog rada obrađeni su i interpretirani podatci geofizičkih mjerenja u bušotinama na području zapadnog dijela Savske depresije koja pripada jugozapadnom dijelu Hrvatskog dijela Panonskog bazenskog sustava. Analizirani su podatci litostratigrafske jedinice pješčenjaka Okoli, člana u kojem su slojevi pješčenjaka proslojeni laporima. Pješčenjaci su predstavljeni kalkarenitnim subgrauvakama te im je temeljem interpretacije geofizičkih mjerenja u bušotinama procijenjena debljina te ukupna i efektivna poroznost. Glavne analize su izvršene u softveru „Interactive petrophysics“, dok su proračunski podatci obrađeni u računalnom programu „Microsoft Excel“. Temeljem rezultata izdvojeno je šest bušotina u kojima pješčenjaci imaju povišenu poroznost i gdje bi trebalo nastaviti istraživanja u smjeru razvoja modela propusnosti.

Abstract (english)

The research contucted in this thesis represents the beginning of exploration of the Okoli sandstones for geoenergy purposes. This thesis framework defines, processes and interprets data from well logs located in the western part of the Sava Depression area, situated in the southwestern Croatian part of the Pannonian basin system. Lithostratigraphic unit Okoli sandstones, is a member characterized by sandstone layers interlayered with marls. Sandstones, represented by calcarenite subgreywacke, were analyzed for their thickness, total porosity and effective porosity estimation based on the well log interpretation. The main analyzes in this research were performed in the "Interactive petrophysics" software, while the calculation of the data were processed in the "Microsoft Excel" software program. Six wells were identified where sandstones show increased porosity and where research should be continued to enable the permeability model development.
