The oil extraction is always followed by the influence on all the components of nature including soils. On the one hand we have the mechanical deformation, leading to its’ hardening and deformation, and transfomations in a whole soil system. On the other hand geochemical changes of soils take place. Any kind of man-made impuct on nature is always followed by its сertain reaction. In such cases the ecological after-effects differ a lot and are always followed by different factors. In soils these changes could be seen through aqua-physical changes, atmosphere pollution, salting and other. These changes are seen because of the provided ecological monitors. In Soviet times these measures were not performed. Rodnikovoye oil field stands among the other oil fields that functions more than 30 years. In this article, the modern geochemical analysis of soils condition is observed. Long-term use didn't affect the geochemical condition of soils. Most of the pollution is made not by the human factor but by the West Siberian natural factors. Soils of Rodnikovoye oil field are poor with microelements. The oil products in soils are on the low pollution rate. Salting also did not observed.
