Abstract
Predmet istraživanja ovog diplomskog rada su dvije različite metode bušenja u uvjetima kontroliranog tlaka: bušenje uz održavanje stalnog tlaka na dno i „Mud Cap“ metoda bušenja. Potreba za ovakvim metodama bušenja javlja se sve češće, zbog izrade bušotina u dosad tehnološki nedostižnim uvjetima dubine, temperature i tlaka, a uz mogućnost iskorištavanja novih ležišta bušenje u uvjetima kontroliranog tlaka dovodi i do povećanja sigurnosti okoliša, ali i ljudi na bušaćim postrojenjima. Rad opisuje teoretsku podlogu dviju spomenutih metoda bušenja, opremu i njihovu primjenu u različitim slučajevima gdje izrada bušotine konvencionalnim bušenjem nije bila moguća zbog nekontroliranih gubitaka isplake ili pak premalog intervala između gradijenata slojnog tlaka i tlaka frakturiranja naslaga.
Abstract (english)
The subject of this thesis are the two main methods of managed pressure drilling (MPD): the Constant Bottomhole Pressure and the ”Mud Cap“ Drilling method. Lately, these unconventional methods have become more frequently used than ever due to greater than ever depth, pressure and temperature conditions of reservoirs. The other advantages of managed pressure drilling are enhanced safety of people on board of drilling structures, as well as environmental protection. The thesis explains the theoretical background of the two methods, necessary equipment and several case studies of MPD use for different types of wells where conventional drilling method proved unsuccessful due to uncontrollable drilling fluid losses or too small a difference between pore pressure and fraction pressure gradient.
