Abstract

Isplaka predstavlja jedan od ključnih elemenata bušaćih operacija te je vrlo bitno ispravno ju dizajnirati kako bi ispunjavala sve potrebne zadatke. Najčešće se koristi isplaka na bazi vode zbog smanjenog utjecaja na okoliš te dostupnosti vode kao baznog fluida za njenu pripremu. Mnogi aditivi koji se dodaju u isplaku kategoriziraju se kao štetni za okoliš te je stoga potrebno razviti nove vrste aditiva. Brojna istraživanja su provedena u tu svrhu koristeći biorazgradivi otpad kao potencijalne aditive. U ovom radu korišten je prah kore mandarine podijeljen u četiri frakcije raspona veličina čestica od 0,063 mm do 0,10 mm, od 0,05 mm do 0,063 mm, od 0,045 mm do 0,05 mm i od 0 mm do 0,045 mm. Također, prah se dodavao u četiri koncentracije: 0,5%, 1%, 1,5% i 2% na volumen vode. Dobiveni rezultati pokazali su da povećanjem koncentracije praha kore mandarine dolazi do smanjenja API filtracija i do 55% dok veličina čestica nije previše utjecala na rezultat. PPT filtracija se dodavanjem praha smanjivala do 39%. Na temelju rezultata može se zaključiti da prah kore mandarine može služiti kao aditiv za smanjenje filtracije na temperaturama do 140°C.

Abstract (english)

The mud represents one of the key elements of drilling operations, and it is very important to design it correctly in order to fulfill all the necessary tasks. Water-based mud is most often used due to the reduced impact on the environment and the availability of water as based fluid. Many additives that are added to the mud are categorized as harmful to the environment and therefore it is necessary to develop new types of additives. Numerous studies have been conducted for this purpose using biodegradable waste as potential additives. In this work mandarin peel powder was used and divided into four fractions with particle sizes ranging from 0.063 mm to 0.10 mm, from 0.05 mm to 0.063 mm, from 0.045 mm to 0.05 mm and from 0 mm to 0.045 mm. The powder was also added in four concentrations: 0.5%, 1%, 1.5% and 2% by volume of water. The obtained results showed that, by increasing the concentration of mandarin peel powder, the API filtration was reduced by up to 55%, while the particle size did not affect the results too much. PPT filtration was reduced by up to 39% by adding powder. Based on the results, it can be concluded that the mandarin peel powder can be used as an additive to reduce filtration at temperatures up to 140°C.
