ABSTRACT

The paper considers main factors of oil hydrocarbons transformation and migration in underground medium. Influence of oil products on changes in redox and acid-alkaline conditions of underground space, as well as on intensification of various forms of microorganisms is shown. Composition and physical-mechanical properties transformation of disperse soils with different water saturation levels are experimentally studied. Failure causes of residual fuel oil storage are analysed. Role of microbial activity in formation of aggressive environment towards structural materials is displayed.

Keywords: underground space; oil hydrocarbons; contamination; microorganisms; sandy-clayey soils; aggregates; biochemical gas formation; quick-sand; corrosion.
