Method of Using Dithiazines and Derivatives Thereof in the Treatment of Wells

摘要

Corrosion of metallic tubulars in an oil, gas or geothermal well may be inhibited by introducing into the well a dithiazine derivative of the formula:;;wherein R14 is a C1-C24 straight chain or branched alkyl group; or a C6-C24 aryl or arylalkyl group; R15 is a C1-C6 alkyl or a C6-C30 aryl or alkylaryl group; and X is chlorine, bromine or iodine. The dithiazine may be isolated from a whole spent fluid (WSF) formed by reaction of hydrogen sulfide and a triazine. Alternately, the whole spent fluid containing dithiazine or dithiazine derivative and a corrosion inhibiting formulation may be used to inhibit corrosion in the well.
