Abstract

Inventia se refera la un fluidizant pentru fluidele de foraj, pe baza de apa, destinat saparii sondelor de pe uscat si de pe mare. Fluidizantul este constituit dintr-un amestec sinergetic, în raport de: 80/20...97/3, de preferinta 90/10, dintre: un homopolimer al acidului acrilic sau al acidului metacrilic, cu greutate moleculara mai mica de 10000 si cu un grad de neutralizare cuprins între 30 si 60%, de preferinta 40...50%, si un polimer cu greutate moleculara mai mare de 500000, din clasa poliacrimamidelor hidrolizate sau nehidrilizate.The invention relates to a water-based drilling fluids for the digestion of land and sea wells. The fluidiser is constituted by a synergistic blend of: 80/20 ... 97/3, preferably 90/10, of: an acrylic or methacrylic acid homopolymer of molecular weight less than 10000 and with a degree of neutralization of between 30 and 60%, preferably 40 ... 50%, and a polymer having a molecular weight greater than 500000, of the class of hydrolysed or non-hydrolysed polyacrylamides.
