METHOD OF OIL WELL CORROSION INHIBITION VIA EMULSIONS AND EMULSIONS THEREFOR

摘要

A method of inhibiting corrosion in an oil well comprises introducing into the well a pourable emulsion comprising a. 50-95% of a discontinuous aqueous phase (such as ordinary water); and b. 5-50% of a continuous oil phase (such as kerosene or similar hydrocarbon) containing a corrosion inhibiting compound (such as an imidazoline). This method results in more consistent corrosion protection, even if longer treatment intervals are used.
