FIELD: chemistry.SUBSTANCE: invention relates to biocides. Biocidal composition contains gluteraldehide and biocidal oxazolidine compound. To realise control over microorganisms in water or water-containing system in the process of oil or gas extraction the system is processed with composition, containing gluteraldehide and biocidal oxazolidine compound. Oxazolidine compound represents 4,4-dimethyloxazolidine. Weight ratio of gluteraldehide to 4,4-dimethyloxazolidine is in the range from 6:1 to 1:9. Oxazolidine compound represents 7-ethylbicyclooxazolidine. Weight ratio of gluteraldehide to 7-ethylbicyclooxazolidine is in the range from 20:1 to 1:20. Water or water-containing system contains sulfides. Microorganisms to be eliminated represent sulfate-reducing bacteria.EFFECT: invention makes it possible to increase efficiency of control over microorganisms in water or water-containing systems, such as systems, detected in the process of oil or natural gas extraction.3 cl, 7 tbl, 3 ex |
