Title (EN) INHIBITING CORROSION IN HIGH TEMPERATURE,HIGH PRESSURE GAS WELLS
(FR) INHIBITION DE LA CORROSION DANS DES PUITS DE GAZ A HAUTE TEMPERATURE ET HAUTE PRESSION
Abstract: front page image
(EN)A relatively nonvolatile, high molecular weight oil soluble corrosion inhibitor carrier produced by adding at least 40 parts by weight of elemental sulfur per 100 parts by weight dialkyl disulfide oil to an amine activated dialkyl disulfide oil which exhibits corrosion inhibition on its own and in combination with conventional oil based corrosion inhibitor additives. Such a carrier is particularly useful in sustaining a liquid film forming phase at bottomhole conditions of high temperature, high pressure gas wells wherein essentially no pretroleum condensate phase exists.
(FR)Un support d"un inhibiteur de corrosion soluble dans l"huile relativement non volatile et de poids moleculaire relativement eleve est produit par addition d"au moins 40 parties en poids de soufre elementaire pour 100 parties en poids d"une huile de bisulfure de dialkyle a une huile de bisulfure de dialkyle activee par une amine, qui presente par elle-meme des caracteristiques d"inhibition de la corrosion est combine a des additifs inhibiteurs de la corrosion conventionnels a base d"huile. Un tel support est particulierement utile pour maintenir une phase de formation d"une pellicule liquide au fond d"un trou tel que des puits de gaz ou regnent des conditions de temperature elevee et de haute pression et ou il n"existe pratiquement aucune phase de condensat de petrole.
