The relevance of the research is caused by the lack of data on the impact of many oil refineries on adjacent soils for specific regions, determined by design and technological features, while the general geochemical specifics of the oil refining industry are studied. The main aim of the research is to identify the features of accumulation in soils and distribution along the profile of some chemical elements specific to the oil refining industry in the area of ​​operation of a relatively new oil refinery by comparing them with data for a background area with similar natural conditions and clarke. Objects of the research are soils of the Tyumen Federal Reserve and the territory of the location of Antipinsky Oil Refinery. Methods: selection and preparation of test plots and soils, determination of the elemental composition by instrumental neutron activation and atomic absorption methods, interpretation of results. Results. The content of Br, Sb, Zn, As, Co in the soils of the eastern part of the Tyumen Federal Reserve and the area of the Antipinsky Oil Refinery, and their distribution along the profile were studied. By comparing the results obtained, an increased content of these chemical elements in the A1 horizon of the soils of the territory where the Antipinsky Oil Refinery is located relative to the Tyumen Federal Reserve and a change in the patterns of their distribution along the profile were revealed. In the soil of the region near the technogenic object, the increased content of the considered chemical elements decreases from top to bottom, which is observed both in absolute values and in concentration coefficients relative to the conditional background data of the soils of the Tyumen Federal Reserve. This indicates the arrival of these elements from the surface. At the same time, in both territories, the content of chemical elements is lower than the clarke, which reflects a relatively low technogenic load in these areas.
