Methods and emulsions for inhibition of oil well corrosion |
摘要 |
A novel method for inhibiting oxygen corrosion in an oil well, and an emulsion useful therein. The method comprises introducing into the well a pourable emulsion comprising about 50 to about 95 volume percent discontinuous aqueous phase, about 5 to about 50 volume percent continuous oil phase, and a corrosion inhibiting amount of a composition comprising a corrosion inhibitor selected from among thiophosphates containing both oxygen and sulfur, pyrophosphates containing both oxygen and sulfur and mixtures thereof.
