Title (EN) REMOVING ELEMENTAL SULFUR FROM HIGH TEMPERATURE,HIGH PRESSURE WELLS
(FR) EXTRACTION DE SOUFRE ELEMENTAIRE DE PUITS A TEMPERATURE ELEVEE ET A HAUTE PRESSION
Abstract: front page image
(EN)A relatively nonvolatile, high molecular weight sulfur solvent produced by adding at least 40 parts by weight of elemental sulfur per 100 parts by weight dialkyl disulfide to an amine activated dialkyl disulfide oil. Such a sulfur solvent is particularly useful in sustaining a liquid phase at bottomhole conditions for high temperature, high pressure wells.
(FR)Un solvant du soufre relativement non volatile et de poids moleculaire eleve est produit par addition d"au moins 40 parties en poids de soufre elementaire pour 100 parties en poids de bisulfure de dialkyle a une huile de bisulfure de dialkyle activee par une amine. Un tel solvant du soufre est particulierement utile pour maintenir une phase liquide au fond d"un trou tel qu"au fond d"un puits ou regnent des conditions de temperature elevee et de haute pression.
