METHOD OF NEUTRALIZING HYDROGEN SULFIDE IN OIL WELL

FIELD: oil and gas production. SUBSTANCE: method consists in injecting specified volume of neutralizing fluid (mixture of 60-90 vol % polyglyceroles formed as by-products in glycerol production and 10-40 vol % sodium chloride aqueous solution) into well followed by forcing the fluid by formation or...

Zusammenfassung:	FIELD: oil and gas production. SUBSTANCE: method consists in injecting specified volume of neutralizing fluid (mixture of 60-90 vol % polyglyceroles formed as by-products in glycerol production and 10-40 vol % sodium chloride aqueous solution) into well followed by forcing the fluid by formation or drainage water into bottom zone. EFFECT: increased efficiency of hydrogen sulfide neutralization during operation period and simultaneously preserved collector characteristics of rocks in bottom zone. 3 cl, 1 tbl
