    摘要： Corrosion of metallic tubulars in an oil, gas or geothermal well may be inhibited by introducing into the well a dithiazine or dithiazine of the formula: wherein R is selected from the group consisting of a C1 to C12 saturated or unsaturated hydrocarbyl group or a C1 to C10 ω-hydroxy saturated or unsaturated hydrocarbyl group; R1 is selected from the group consisting of a C1-C24 straight chain or branched alkyl group or a C1-C24 arylalkyl; R2 is selected from the group consisting of X-R4-X, R4 being a C1-C6 alkyl group; and X is chlorine, bromine or iodine. The dithiazine may he isolated from a whole spent fluid formed by reaction of hydrogen sulfide and a triazine. Alternately, the whole spent fluid containing the dithiazine may be introduced into the well. The dithiazines of formulae (II) and (III) are quaternized derivatives of the dithiazine of formula (I). In addition, the dithiazine or whole spent fluid or quaternized dithiazine may be formulated with at least one component selected from alkyl, alkylaryl arylalkyl or arylamine quaternary salts; mono or polycyclic aromatic amine salts; imidazoline derivative or a quaternary salt thereof; a mono-, di- or trialkyl or alkylaryl phosphate ester; or a monomeric or oligomeric fatty acid.
