Abstract

Abstract Translated from English Composition associative hydrophobe d'un copolymère comprenant un monomère éthyléniquement insaturé soluble dans l'eau, tel un acrylamide, et un monomère amphiphile éthyléniquement insaturé, tel le méthacrylate de docécyl poly(oxyéthylène)10, qui est particulièrement efficace pour accroître la viscosité de saumures ou d'autres supports aqueux contenant des sels ou d'autres électrolytes. Ces copolymères sont par conséquent utiles dans des fluides de régulation de la mobilité et des fluides de fracture permettant une meilleure récupération du pétrole et en tant qu'agents réducteurs de traînée. Hydrophobic associative composition of a copolymer comprising an ethylenically unsaturated water-soluble monomer, such as an acrylamide, and an ethylenically unsaturated amphiphilic monomer, such as docecyl poly (oxyethylene) methacrylate, 10 which is particularly effective in increasing the viscosity of brines or other aqueous carriers containing salts or other electrolytes. These copolymers are therefore useful in mobility control fluids and fracture fluids allowing better recovery of petroleum and as drag reducing agents.
