[Sulfate reduction and the water-soluble organic substances in a flooded petroleum bed].
The paper presents the analytical data for the hydrochemical and microbiological composition of the water in a stratum undergoing changes as a result of artificial flooding. The highest accumulation of biogenic H2S and the carbon of dissolved organic substance was found in diluted bed waters with mineralization of 17.17 g/litre. The composition of the bitumen carbon of dissolved organic substances changed with dilution of the stratum brine. The data thus obtained suggest the existence of an indirect relationship; oxidized dissolved organic substance--the rate of sulphate reduction. The nature of organic substance appearing in the petroleum stratum is discussed.
