Abstract

Cette invention se rapporte au domaine de l'extraction des produits pétroliers et concerne plus précisément des compositions et des procédés qui permettent de préparer des émulsions de type eau-huile. Ces émulsions peuvent être utilisées afin d'ajuster le profil d'injectivité de puits d'injection et/ou d'isoler l'afflux d'eau dans des puits de pétrole. Afin d'accroître la stabilité cinétique et agrégative des émulsions eau-huile ainsi formées, on utilise en qualité d'émulsifiant du pétrole brut, lourd et à base d'asphalte gommant, qui possède un contenu élevé d'au moins 100 νg/g de complexes de porphyrine et qui n'a été soumis à aucun traitement thermochimique. On utilise en qualité de phase huileuse un mélange d'hydrocarbures liquides à base de paraffine ainsi qu'un solvant lourd, ceci dans des proportions en volume telles que la densité du mélange (de la phase huileuse) soit égale à la densité de l'eau servant à préparer l'émulsion de type eau-huile.
