FIELD: oil and gas industry. SUBSTANCE: sulfate-reducing bacteria ( 0.5-1.0 wt. -% ) and microbiologically treated sewage - the rest are added to composition consisting of methane-tanks. Preliminary SRB are cultured in microbiologically treated sewage under anaerobic conditions for 10-14 h. The sulfate-reducing bacteria are mixed with solution containing methane-tank bacteria and biologically treated sewage, which is treated at 90-100 C. Bacteria from species Desulfovibrio are used as sulfate-reducing bacteria. By treatment of sulfated carbonate gas stratum hole output is increased by 2.3-fold. EFFECT: improved hydrocarbon-displacing capability. 3 cl, 2 tbl
