Abstract
Izrada bušotina uključuje složeni niz poslova s ciljem dosezanja ležišta ugljikovodika ili geotermalne vode. Kako bi bušotina bila kvalitetno i sigurno izrađena te omogućila buduću eksploataciju ležišta, potrebno ju je pravilno konstruirati. Naftne kompanije posljednjih desetljeća pokušavaju optimizirati uobičajene prakse pri projektiranju bušotina te tako uštediti financijska sredstva. Jedan od dijelova projektiranja konstrukcije jest i projektiranje zacjevljenja bušotine, odnosno pravilni odabir promjera i dubina ugradnje zaštitnih cijevi određenih mehaničkih karakteristika kako bi odolijevale promjenjivim uvjetima tijekom cijelog radnog vijeka bušotine. Trošak nabave zaštitnih cijevi te njihova ugradnja i cementiranje predstavlja veliki dio troškova izrade bušotine. Stoga, projektantski je izazov dizajnirati takvo zacjevljenje koje će izdržati sva naprezanja uz što manji trošak. U radu je obrađen teoretski pristup pri konstruiranju zacjevljenja i mogući uzroci odstupanja završne konstrukcije bušotine od projektiranih vrijednosti. U sklopu toga, izrađene su i uspoređene dvije konstrukcije bušotine X na istražnom polju Y, s različitim brojem nizova zaštitnih cijevi. Za potrebe projektiranja konstrukcije bušotine korišten je softverski paket Landmark, modul StressCheckTM.
Abstract (english)
Drilling wells involves a complex series of operations with the goal of reaching hydrocarbon or geothermal water reservoirs. In order for the well to be properly and safely made and to enable the future exploitation of the reservoir, it must be correctly constructed. In recent decades, oil companies have been trying to optimize the usual practice when constructing wells and thus save financial resources. One part of well construction is the casing design, that is, the correct selection of the diameter and installation depth of casing strings with certain mechanical characteristics in order to withstand changing conditions during the entire life of the well. The cost of procuring casings and their installation and cementing represents a large part of the well construction costs. Therefore, the challenge is to design such casing strings that will withstand all stresses with the least possible cost. The thesis deals with the theoretical approach of casing design and the possible causes of the deviation of the final construction of the well from the designed values. As a part of this, two constructions of well X on the exploratory field Y, with different number of casing strings, were made and compared. Landmark software, the StressCheckTM module, was used for the well construction purposes.
