Abstract

Učestalim remontnim radovima na naftnim i plinskim bušotinama izdvajaju se znatna financijska sredstva za održavanje dnevno pridobive količine ugljikovodika na određenoj razini, te su stoga nužne mjere racionalizacije u sustavu koje bi takve radove sveli na minimum čime bi se povećala isplativost cijelog projekta. Poglavito je to slučaj na starim poljima u završnoj fazi eksploatacije kao što je naftno polje Kloštar na kojem je umjetno podizanje kapljevine dubinskim klipnim sisaljkama dominantna metoda. U tu svrhu, na spomenutom polju instalirani su dozirni uređaji pogonjeni gredom njihalice kojima je omogućeno doziranje kemijskih aditiva među kojima su i aditivi za inhibiranje parafinskih naslaga. U okviru ovog diplomskog rada napravljen je generalni osvrt na probleme vezane uz odlaganje parafina na proizvodnoj opremi, metode uočavanja problema, te prevencije i uklanjanja istih.

Abstract (english)

Maintaining oil production requires frequent service jobs regarding well equipment, cleanouts, etc. that can be quite costly. The goal is to keep such interventions to a minimum, especially in late-stage production period oil fields like the Kloštar field. The dominant artificial lift method on the Kloštar oil field are sucker rod pumps. To achieve maintenance cost reductions on such installations, chemical dosing pump devices have been installed on sucker rod pumps to continuously inject additives such as paraffin inhibitors, directly into the wellbore. A review of the problems with paraffin precipitation, detecting methods, prevention and removing methods is done as well.
