Abstract

U ovom radu su analizirani i interpretirani seizmogeološki podatci iz pet bušotina sa područja istočne Hrvatske, radi boljeg razumijevanja geološke prošlosti i prepoznavanja geoloških resursa. Pri tome je korišten 3D seizmički volumen popraćen geofizičkim podatcima mjerenja u pet bušotina kao i geološki podatci prikupljeni istražnim radovima u bušotini. Od geofizičkih podataka u bušotinama za korelaciju istraživanih naslaga korištene su karotažne krivulje spontanog potencijala, RT otpora i prirodne gama radioaktivnosti. Interpretirano je devet horizonata od kojih je izdvojeno četiri kao relevantnih za istraživanje. Za četiri izdvojena horizonta napravljene su strukturne vremenske karte i karte Root mean square atributa i atributa koherencije. Napravljene karte pokazuju prisutnost kanala i taložnih formi okarakteriziranih kao sediment waves (pješčani valovi). Analizom podataka bušotinskih jezgri i krivulja spontanog potencijala dokazana je prisutnost pretežito lapora i turbidita na području istraživanja. Svi rezultati upućuju na postojanje rezervoarskih stijena koje bi mogle imati dobro zatvaranje.

Abstract (english)

This work focuses on the analysis of seismo-geological data from five wells drilled in eastern Croatia, with the goal of better understanding the geological history and identifying geological resources in the area. The work presented in this thesis integrates 3D seismic data, well data and geological data from well cores. Well data used in the work are wellbore logs of spontaneous potential (SP), resistivity, and gamma ray. From nine horizons interpreted in this work, four were selected as important for the research. Structural time maps, Root Mean Square (RMS) maps, and coherence maps were made for each of the selected horizons. The maps show the existence of channels and sedimentary forms characterized as sediment waves. Core data and SP logs have proven the existence of mostly marls and turbidites in the research area. The results suggest the existence of reservoir rocks that could have a good seal in regard of potential hydrocarbon research.
