Abstract

On utilise des composés hydrocarbures oléfiniquement insaturés, au moins pour la plupart linéaires et alpha-stables, avec des points d'inflammation d'au moins 80 DEG C, comme phase huile ou composant de la phase huile de produits fluides de traitement de puits à base d'huile ou d'eau. Les produits correspondants de lavage de puits contiennent, outre les alpha-oléfines, d'autres phases huile faisant partie des produits de traitement de puits, se caractérisent par leur compatibilité avec l'environnement et par leur dégradabilité aussi bien aérobie qu'anaérobie. Parmi les phases huile mixtes les plus appropriées on compte les alcools oléophiles, les éthers et les esters correspondants d'acide carboxylique et/ou carbonique.
