Abstract

New copolymers soluble in an aqueous medium, which are stable in a highly concentrated medium of Bronsted-Lowery acids. These copolymers are used as acid lubricants in the field of oil and natural gas boring. The copolymer according to the invention contains in its macromolecule, in statistical distribution, at least 5% by weight of units having each a formylamino group (according to A) and at least 10% by weight of units having each an aminocarbonyl group (according to B).
