Abstract

Tehnologija izrade bočnih (engl. re-entry) bušotina i tehnologija izrade bušotina malog promjera (engl. slim hole wells) svoja prva pojavljivanja u naftnoj industriji zabilježile su otprilike u isto vrijeme, sredinom prošloga stoljeća, međutim niti jedna od tehnologija nije značajnije ušla u bušaću praksu sve do početka 1990-ih godina, kada se došlo do spoznaje o mogućim uštedama koje omogućuju izrade takvih bušotina.
U nastavku ovoga rada bit će predstavljen kratki povijesni razvoj, prednosti i nedostaci te načini izrade bušotina malog promjera i bočnih bušotina. Isto tako detaljnije će se obraditi primjena savitljivog tubinga u svrhe bušenja jer se primjenom te tehnologije omogućava izrada bočnih bušotina malog promjera. Također su navedeni primjeri izrade bušotina malog promjera korištenjem savitljivog tubinga, te primjer izrade bočne bušotine malog promjera u Hrvatskoj korištenjem konvencionalnog sklopa alatki.

Abstract (english)

The re-entry borehole technology and the slim hole well technology appeared in the petroleum industry roughly at the same time, in the middle of the 20th century. However, none of the two were used to any great extent in well drilling until the beginning of the 1990s, when contractors discovered the potential for savings by using these technologies.
This thesis briefly describes the historical development, advantages and disadvantages and methods of drilling slim hole and re-entry wells. Also, the application of coiled tubing for drilling purposes will be elaborated upon, since the utilisation of this technology has made the drilling slim hole re-entry wells possible. The thesis also contains examples of slim hole re-entry drilling using coiled tubing technology and conventional bottom-hole assembly in a well in Croatia.
