Abstract

Ovaj rad obrađuje tehnologiju proširivih zaštitnih cijevi, točnije proces njihove cementacije. Na početku je dan kratki povijesni pregled razvoja ove tehnologije od idejnih začetaka do tehnologije koja se u posljednjih dvadesetak godina naveliko koristi u naftnoj industriji. Opisane su vrste proširivih zaštitnih cijevi kao i područja njihove primjene. Cementacija proširivih zaštitnih cijevi u određenoj se mjeri razlikuje od cementacije klasičnih zaštitnih cijevi stoga su izazovi, specifičnosti i alternativna rješenja vezana uz njihovu cementaciju glavni predmet ovog rada. Sve teoretske tvrdnje i razmatranja te preporuke za obavljanje cementacije proširivih zaštitnih cijevi potkrjepljene su s nekoliko primjera iz prakse.

Abstract (english)

This thesis explores the technology of expandable casings, especially the cementing of such tubulars. A brief historical overview regarding the development of this technology from its conceptual beginnings to the technology which is now widely used in the petroleum industry is provided. Different types of expandable casings are described along with their scope of application. The cementation process of expandable casings is somewhat different from the cementation process of regular casings, thus challenges, specifics and alternative solutions for cementing expandable casings will be the main focus of this thesis. The theoretical part of this paper is supported by several case studies.
