Key words: hydrocarbon pollution, subsoils, experimental research.

This research is devoted to the experimental study of hydrocarbon pollution spread in different kinds of subsoils. Hydrocarbon stress was created of the engine oil, subsoils are presented in small and medium size sand, silty fine clay, in air-dry state and of different humidity. It was founded that the depth of hydrocarbon contamination distribution in soils is determined by lithology. For all soils the maximum contamination occurs in the first day, and the maximum rate of penetration of hydrocarbons is observed in the first 4 hours after the emergency oil spill on the earth's surface. Clay with humidity above the limit rolling prevent the penetration of hydrocarbons in the soil and can act as oil resistance.
