Patent

CA 2449083

The present invention relates to methods and compositions for increasing the effective temperature range for viscosified fluids, including particularly fluids that have been viscosified by the addition of a natural or a natural derivative polymer. In one embodiment, the present invention relates to a method for increasing the effective temperature range for a polymer- viscosified fluid used as a well fluid, which includes adding a miscible tertiary, secondary, and/or primary amine compound into a polymer solution. In another embodiment, the present invention relates to a thermally stable well fluid, which includes a polymer, a solvent, and a tertiary, secondary, and/or primaryamine miscible in the solvent.

La présente invention porte sur des procédés et sur des compositions utilisés pour augmenter la plage de températures efficaces de fluides viscosifiés, à savoir des fluides qui ont été viscosifiés par addition d'un polymère naturel ou d'un polymère dérivé. Selon une réalisation, cette invention porte sur un procédé permettant d'augmenter la plage de températures efficaces d'un fluide viscosifié par un polymère et utilisé comme fluide de forage, ce procédé consistant à ajouter à une solution polymère un composé d'amine miscible tertiaire, secondaire et/ou primaire. Selon une autre réalisation, l'invention porte sur un fluide de forage thermiquement stable comprenant un polymère, un solvant et un amine tertiaire, secondaire et/ou primaire miscible dans un solvant.
