Abstract

Invenţia se referă la un aditiv pentru fluide de foraj, pe bază de apă nemineralizată sau cu mineralizare moderată, cu efect sinergic de reducător de filtrare şi dispersant. Aditivul este constituit dintr-un copolimer grefat de tip acrilat de sodiu-poli -alfa glucoză, cu grad de policondensare de 10...100, de preferinţă 15...30, cu o masă moleculară medie de 4000...25000, de preferinţă 5000...8000, şi un raport de copolimerizare gravimetrică de 80/20...60/40, de preferinţă 65/35.
