Abstract

Jedna od najčešćih metoda povećanja iscrpka nafte je utiskivanje ugljikovog dioksida (CO2) u uvjetima miješanja. Utisnuti CO2 pri visokom tlaku i ležišnoj temperaturi miješa se s naftom tvoreći manje viskozan fluid s nižom međupovršinskom napetosti između fluida i stijene od originalne nafte. U radu je opisan način određivanja perspektivnosti ležišta za povećanje iscrpka nafte utiskivanjem CO2 i vrste procesa miješanja. Simulacijski program Eclipse korišten je za simulaciju utiskivanja CO2 u usku cijev. Rezultati su korišteni za određivanje minimalnog tlaka miješanja CO2 i ležišne nafte, opasivanja procesa miješanja i kretanja komponenata iz sastava nafte tijekom istiskivanja.

Abstract (english)

One of the most widely used methods for enhanced oil recovery is CO2 miscible flooding. CO2 injected at high pressure and temperature achieves miscibility with oil, creating fluid with lower viscosity and interfacial tension forces between fluid and rock than the original oil. In this work reservoir screening criteria for CO2 miscible flooding enhanced oil recovery and different types of miscibility processes are described. Eclipse reservoir simulation software was used for simulating the injection of CO2 in slim tube. The results were used for determining minimum miscibility pressure for CO2 and oil, describing miscibility process and movement of oil components during flooding.
