Abstract
Prezenta inventie se refera la un produs utilizat ca dispersant pentru sistemele coloidale de tipul bentonita-apa, fluide de foraj, de perforare, de packer, fluide de fisurare s.a. Solutia are la baza un produs obtinut prin cuplarea unui derivat acrilic, de tipul acid metacrilic, cu un amestec de lignosulfonat de amoniu, humat de sodiu si un tanin vegetal, în prezenta unui initiator de reactie, de tipul apa oxigenata. Dispersantul, conform prezentei inventii, îsi gaseste aplicare directa în procesul de sapare a sondelor de titei si gaze, în special a sondelor de pe mare.
