Abstract

Od prepoznavanja potencijala nanočestica u naftnoj industriji, iz godine u godinu njihov značaj te broj eksperimenata i terenskih testnih primjena sve više raste. Nanočestice su čestice čiji se promjeri kreću u rasponu od 1 do 100 nanometara, gdje jedan nanometar iznosi 10-9 metara. Ukoliko se pojedini aditivi ili neki materijali koji se inače standardno ne koriste u naftnoj industriji prevedu u veličine nanočestica, oni dobivaju nova određena svojstva ili se njihovi učinci poboljšavaju te ubrzavaju. Ovaj rad opisuje nekoliko provedenih eksperimenata i pokusa s nanočesticama u isplaci te njihov učinak na poboljšavanje svojstva isplake, s naglaskom na provjeru utjecaja nanočestica na filtraciju te debljinu isplačnih obloga.

Abstract (english)

Ever since discovering the potential of nanoparticles in petroleum industry, their significance, as well as the number of experiments conducted and field applications, has been growing yearly. Nanoparticles are particles whose diameters span from 1 to 100 nanometers (1 nanometer equals 10-9 meters). If certain additives or other materials which aren't usually used in the petroleum industry get translated to the size of nanoparticles, they can either acquire new properties or improve and speed up their effects. This work describes several conducted experiments regarding the effect of improvements of drilling fluids using nanoparticles, with the focus on reducing the amounts of filtration and mud cakes.
