Abstract RU 2138628 C1

FIELD: oil production industry. SUBSTANCE: reagent for suppressing growing of sulfate-reducing bacteria in oil bed being flooded is represented by product resulted from interaction of formaldehyde-containing substance and monoethanolamine at their molar proportion being equal to 1:0.8-1.2 in terms of formaldehyde. Application of aforesaid reagent enhances efficiency of suppressing sulfate-reducing bacteria by using lower amounts of reagent. EFFECT: higher efficiency. 2 tbl, 4 ex
