Abstract

Temeljna svrha izrade horizontalnih (vodoravnih) bušotina, tj. bušotina kojima proizvodni dio kanala zauzima horizontalan položaj u prostoru, jest povećanje dodira kanala bušotine s ležištima nafte i/ili plina, te na taj način povećavanja proizvodnosti tih bušotina. Izrada bušotina velikog dosega postao je čest način izrade bušotine koji omogućava ekonomičan pristup rezervama koje su prethodno bile izvan dohvata, uz postojeću infrastrukturu, i smanjuje utjecaj proizvodnih postrojenja na okoliš. Većina horizontalnih bušotina izrađuju se zbog razrade raspucanih stijena u ležištu, ležišta s potencijalnim problemima konusiranja vode i/ili plina te ležišta s proizvodnim naslagama male debljine. U radu su prikazani primjeri izrade horizontalnih bušotina velikog dosega, oprema koja je pri tom korištena, te problemi koji se javljaju prilikom izrade ovakvih bušotina.

Abstract (english)

Abstract: The main purpose of drilling horizontal wells i.e. wells who's production comes from the horizontal section , it enhances the wellbore kontakt with the reservoir containing oil and/or gas, and by that increasing the production of these wells. Extended-reach drilling (ERD) has become a common means to access reserves economically from existing infrastructure, that were previously out of reach, and reduce the environmental footprint of production facilities. Most of the horizontal wells are drilled to develope the cracked rocks in the reservoir, reservoirs with potential water coning problems and reservoirs with small reservoir production thickness. The paper presents examples of extended reach wells, equipment that was used to drill, and the problems that occur when drilling such wells.
