METHOD AND COMPOSITION FOR INHIBITING CORROSION IN HIGH TEMPERATURE, HIGH PRESSURE GAS WELLS

摘要

ABSTRACT OF THE DISCLOSUREA relatively nonvolatile, high molecular weightoil soluble corrosion inhibitor carrier produced by addingat least 40 parts by weight of elemental sulfur per 100parts by weight dialkyl disulfide oil to an amine acti-vated dialkyl disulfide oil which exhibits corrosion inhi-bition on its own and in combination with conventional oilbased corrosion inhibitor additives. Such a carrier isparticularly useful in sustaining a liquid film formingphase at bottomhole conditions for high temperature, highpressure gas wells wherein essentially no petroleum con-densate phase exists.79172ART0178
