Abstract

U ovom diplomskom radu napravljena je analiza remontnih radova u periodu od 2011. godine do 2022. godine na primjeru jednog naftno plinskog polja u Republici Hrvatskoj. U radu su opisane metode pridobivanja kapljevine na razmatranom polju te su opisani dijelovi proizvodne opreme koji se koriste za pojedine metode pridobivanja kapljevine. Polja koja su prestala eruptivno proizvoditi vlastitom energijom iz ležišta, proizvode i dalje ali uz primjenu mehaničke metode pridobivanja kapljevine. Najstarija mehanička metoda pridobivanja kapljevine je dubinska klipna sisaljka s klipnim šipkama. Uz tu metodu na ovom naftno plinskom polju koriste se i centrifugalne sisaljke. Samo na pojedinim bušotinama sisaljke s klipnim šipkama zamijenjene su sa linearnim sustavom podizanja kapljevine, ovaj sustav u cjelini je puno bolji jer troši manje električne energije i radi u više različitih frekvencija koje se reguliraju preko kompjutera. Na temelju prikupljenih podataka provedena je analiza kolika količina fluida nije proizvede na tijekom čekanja na remont opreme i za vrijeme samog remonta, koliko se vremena čekalo i koliko je trajao remont opreme te je procijenjena isplativost remonta.

Abstract (english)

This thesis presents an analysis of repair works in the period from 2011 to 2022 on the example of an oil and gas field in the Republic of Croatia. The thesis describes the methods of fluid extraction in the considered field and provides an overview of the components of production equipment used for each method of fluid extraction. Fields that have ceased to produce fluid naturally from reservoirs continue to p roduce using mechanical methods of fluid extraction. The oldest mechanical method of fluid extract ion is the deep piston pump with piston rods. In addition to this method, centrifugal pumps are also used in this oil and gas field. Only in certain wells, piston pumps have been replaced with a linear fluid lifting system, which is overall more efficient as it consumes less electrical energy and operates at various frequencies regulated by a computer. Based on the collected data, an analysis was conducted to determine the amount of fluid not produced during equipment maintenance and repair, the waiting time for repairs, the duration of equipment maintenance, and the cost effectiveness of the repairs.
