Abstract.Purpose of this study was to determine geochemical regularities of changes in chemical composition of oil- and gas-contained waters in the Dnieper-Donets depression and to explain specific distribution of halogens in the waters. To study the water chemical composition, methods of chemical and potentiometric analysis, and atomic absorption were used; the findings were interpreted with the help of basic programs of statistical analysis. The findings show that oil water and gas-condensate water from the Talalaivk Rybalsk field and Glinsk Solohovsk field in the gas- and oil-contained regions are highly salt (mineralization is above 150 g/dm³). In the northwestern part of the territory (Velikobubnovsk and Talalaivk deposits), waters show high average content of chlorine and bromine (160 g/dm³ and 0,18 g/dm³, respectively), and in the southeastern part (Opishnyansk deposit) − high average iodine content (0,018 g/dm³); such high contents exceeding 2−3 times figures for other fields can be explained by presence of tectonic disturbances. Since the waters from all oil and gas deposits feature direct correlation between salinity and chlorine, bromine and iodine content it can be concluded that it is reasonable to take into account a halogen component in order to identify any oil- and gas-contained areas. Further study of the regularities of halogens distribution in groundwater of the oil and gas fields will improve hydrogeochemical methods for searching the gas- and oil field.
