Reducing the content of sulfides in industrial liquids oil-bearing COLLECTORS

摘要

1. A method for processing oil-bearing reservoir, comprising: a) providing an injection well in the oil reservoir; b) introducing an aqueous solution containing at least one inorganic oxidizing agent, into an injection well, wherein said solution flows through the borehole in the oil-bearing reservoir and comes in contact with a mixture of water and oil in the oil reservoir, where it forms a technical liquids; and c) extraction technical fluid through at least one production well which is in contact with the injection well, wherein the concentration of sulfide in the fluid technology reduced over the concentration of sulfide in the technical fluids obtained without performing step (b) .2. The method of claim. 1, wherein the inorganic oxidizing agent has a standard potential is higher than half reaction -0.478 B.3. 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. The method of claim. 1, wherein the inorganic oxidant comprises nitrate ions, nitrite ions or nitrate ions, and a mixture nitrita.6. The method of claim. 5, where the total molar concentration of nitrate ions, ions of nitrite or a mixture of nitrate 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 an aqueous solution of step (b). 7. The method of claim. 5, rD
