Abstract
Minimalni tlak miješanja ključni je parametar na temelju kojeg se planiraju uvjeti utiskivanja plinova kako bi se postigao dodatni iscrpak nafte kojoj se smanjila pokretljivost tijekom proizvodnje ispod tlaka zasićenja. Iz dostupnih laboratorijskih podataka o nafti, tj. laboratorijske studije utiskivanja nafte, uzeti su podaci za usklađivanje s onima koji se mogu dobiti simulacijom PVT uvjeta, pomoću jednadžbe stanja. Kako je za minimalni tlak miješanja u ležištu potrebno uzeti u obzir prostorne raspodjele zasićenja fluidima tijekom utiskivanja, a jednadžba stanja opisuje samo svojstva fluida, sami minimalni tlak miješanja se odredio korelacijom, a ostala svojstva (viskoznost, gustoća, faktor bubrenja) su određena pomoću podešene jednadžbe stanja. Hipoteze navedene u uvodu su potvrđene, tj. da minimalni tlak miješanja (korelacija Cronquista je dala izvrsno slaganje s laboratorijskim podacima) i volumetrijske promjene tijekom utiskivanja CO2 (modificirana Peng-Robinsonova jednadžba stanja daje vrlo dobro poklapanje s podacima iz laboratorija) mogu biti određeni korelacijom i numerički, samo korištenjem jednadžbe stanja.
Abstract (english)
Abstract: Minimum miscibility pressure is a key parameter for gas injection planning in order to achieve enhanced oil recovery that became less mobile during the production below saturation pressure. From laboratory data on oil, i.e., laboratory injection studies, the data were taken for matching with those that can be obtained by simulating the same PVT conditions, by using the equation of state. As for minimum miscibility pressure in a reservoir spatial distribution of fluids saturations during the injection is required, and the equation of state describes only the properties of the fluids themselves, a minimum miscibility pressure was determined by empirical correlation, and other properties (viscosity, density, swelling factor) were determined by using modified equation of state. Hypothesis stated in the introduction have been confirmed, and that is that minimum miscibility pressure (Coronquist's correlation gave excellent matching with data measured in a lab) and volumetric changes during the CO2 injection into reservoir oil (in this work modified Peng-Robinson equation of state showed very good matching) can be obtained by correlation and numerically i.e. only by equation of state.
