This article explains that in recent years with the growth of oil and gas to the environmental hazard of the fuel and energy complex. At the moment, due to the intensification of oil and gas reservoir associated saline water is one of the priority sources of pollution, and in particular the soil. The aim of our study was to investigate the chemical composition, physical and chemical properties of the produced water and its impact on soil and vegetation of a spill. The objects of our study were produced water samples were selected from different oil fields in the south-eastern part of the Republic of Kalmykia. The results of the analysis of hydrochemical study of saline formation water, and based on them clearly shows the distribution of ions in the test samples. Reported high concentrations of ions in the test samples of formation water causes soil salinity. The article shows the relationship of hydrogeochemical parameters (different genetic factors and factor metamorphism) and physico-chemical properties of this formation water located in the south-eastern part of the Republic of Kalmykia. On the basis of analysis of the investigated samples of formation water were characterized in terms of different classifications in petroleum hydrogeology. Based on these results, it was concluded and noted that hydrochemical composition of saline water reservoir dramatically changes the state of ecosystems, and in particular, leads to the degradation of soil biocenosis and a spill of mineralized formation water.
Key words: reservoir water,hydrochemical composition,hydrogeochemical indicators salinity,
