    • 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.
    • 通过向井中引入下式的二硫嗪衍生物可以抑制金属管在油,气或地热井中的腐蚀:其中R14是C1-C24直链或支链烷基; 或C 6 -C 24芳基或芳烷基; R 15是C 1 -C 6烷基或C 6 -C 30芳基或烷芳基; X是氯,溴或碘。 二硫嗪可以与通过硫化氢和三嗪的反应形成的整个废流体(WSF)分离。 或者,可以使用含有二硫嗪或二噻嗪衍生物和腐蚀抑制剂的整个废流体来抑制井中的腐蚀。
