A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more co-polymers of N-alkyl (alkyl)acrylamide monomers and one or more cationic monomers selected from acid and alkyl chloride quaternary salts of N,N-dialkylaminoalkyl (meth)acrylates and N,N-dialkylaminoalkyl (meth)acrylamides.

L'invention porte sur un procédé d'inhibition d'hydrates dans un fluide comprenant de l'eau et un gaz. Ce procédé comprend l'addition au fluide en une quantité efficace pour l'inhibition d'hydrate d'une composition comprenant un ou plusieurs copolymères de monomères N-alkyl(alkyl)acrylamides et un ou plusieurs monomères cationiques choisis parmi des sels quaternaires de chlorure d'acide et d'alkyle de N,N-dialkylaminoalkyl(méth)acrylates et de N,N-dialkylaminoalkyl(méth)acrylamides.
