Description (Dublin Core)

eng After primary oil recovery in reservoirs remains about 70% of unexploited oil. To improve the recovery of the remaining reserves, injection of a fluid provide the extra energy in a mchunical form. Oil displacement can he achieved by gas injection of lean natural gas, mainly methane, carbon dioxide etc. Oil displacement can be in immiscible or miscible conditions. This paper deals with mechanism of miscible gas drive. On the basis of simulation of the oil displacement process by gas injection into oil field Žutica the character of process, i. c. a degree of miscibility or immiscibility between the injected fluid and reservoir oil was determined.
hrv Smanjenjem produktivnosti bušotina nakon primarne faze proizvodnje u ležištu zaostaje više od 70% početne količine nafte. Dalje povećanje iscrpka preostale nafte moguće je postići utiskivanjem fluida u ležište čime se dobiva dodatna energija u ležištu u mehaničkom obliku. Istiskivanje nafte postiže se utiskivanjem suhog prirodnog plina, pretežito metana, ugljik dioksida i dr. Proces istiskivanja može se odvijati u uvjetima nemiješanja i miješanja fluida ovisno o ležišnom tlaku i temperaturi. Opisani se mehanizmi istiskivanja nafte utiskivanjem plina u uvjetima miješanja. Za naftno polje Žutica na temelju simulacije istiskivanja nafte utiskivanjem plina određen je karakter procesa odnosno stupanj miješanja ili nemiješanja utisnutog fluida i ležiš ne nafte.
