Corrosion destroying of equipment manifests itself in a later stage during exploration of oil fields, when extracted oil is watered and properties of separating stratal water, during extraction, collection and preparation of oil, significantly change, particularly increases in sulfate reducing bacteria (SRB) and concentrations of corrosion aggressive gas products from their activity – hydrogen sulfide. As we know, most corrosion inhibitors and biocides which are applied in oil- gas extraction, consist of nitrogen containing substances, as amino alcohols, imidozolines, amides, etc. The aim of this work is to find an efficient method for obtaining new effective biocides for suppression of sulfate reducing bacteria. Biocide properties of nitrogen containing substances on the basis of olefins have been studied in SRB (sulfate reducing bacteria) and H2S containing medium. Correlation between protective properties of reagent and origin of initial components has been established.

Keywords: biocide, sulphate reducing bacteria, hydrogen sulphide, olefin, amino alcohol
