Abstract

Tehnologija savitljivog tubinga je tijekom godina znatno napredovala te je njegova primjena višestruka. Kemijske stimulacijske obrade ležišnih stijena učestalo se koriste još od 1930.-ih godina u svrhu poboljšavanja proizvodnosti naftnih i plinskih bušotina uklanjanjem oštećenja stijena. Obuhvaćaju obrade utiskivanjem kiseline odnosno kiselinsku obradu i obradu utiskivanjem površinski aktivnih tvari, deemulgatora te raznih organskih i anorganskih otapala. Upravo je jedna od najboljih primjena savitljivog tubinga njegovo korištenje za postavljanje kiseline tijekom kiselinske obrade stijene. Kiselinska obrada donosi brojne korozijske probleme na čeliku. Prvi dio ovog rada daje pregled same tehnologije i postrojenja za rad sa savitljivim tubingom, a u drugom dijelu fokus je na korozijskim izazovima koje kiselinska obrada ležišnih stijena donosi.

Abstract (english)

Coiled tubing technology has advanced significantly over the years and it's application is multiple. Chemical stimulation treatments od bedrocks have been frequently used since the 1930s in the purpose of improving oil and gas well productivity by removing bedrock damage. Chemical stimulation treatments include matrix acidizing and the injection of surfactants, demulsifires and various organic and inorganic solvents. One of the best applications of coiled tubing technology is matrix acidizing. Matrix acidizing causes a number of corrosion problems on the steel of which coiled tubing is made. The first part of this paper provides an overview of the technology and components of the coiled tubing unit, in the second part the focus is on corrosion challenges that come with matrix acidizing.
