Reducing the content of sulfides in industrial liquids IN THE OIL RECOVERY

摘要

1. A method for processing liquid technical in a production well comprising: a) providing an oil production well in the oil reservoir, having a casing and the production tubing; b) introducing an aqueous solution containing at least one inorganic oxidizer, a well casing, wherein said solution flows along the casing and comes into contact with the technical fluid in the wellbore below the production tubing; and c) to obtain technical service pipe by fluids, wherein the concentration of sulfide in the fluid technology reduced over the concentration of sulfide in the technical liquid obtained without the step (b) .2. A method according to Claim. 1 wherein the inorganic oxidizer is a standard half cell potential higher than the reaction -0.478 B3. The method of claim. 2, wherein the inorganic oxidizer selected from the group consisting of permanganates, persulfates, inorganic peracids, chromates, bromates, iodates, chlorates, perchlorates, chlorites, hypochlorites, peroxides and inorganic oksidov.4. The method of claim. 3, where the inorganic oxidant is selected from the group consisting of chlorine dioxide, hypochlorite, peroxide and persulfate vodoroda.5. A method according to Claim. 1 wherein the inorganic oxidizer vklyuchaetnitrat ions, nitrite ions or a mixture of nitrate and nitrite ions ionov.6. The method of claim. 5, where the total molar concentration of nitrate ions, nitrite ions or a mixture of the nitrate ion and nitrite ion is at least five times higher than the molar concentration of sulphide in the technical fluids in the production well, measured prior to administration of the aqueous solution in step (b) .7. The method of claim. 5, wherein at IU
