摘　　要：This paper, based on the fundamental inorganic chemical and organic geochemical characteristics of oilfield waters from the Turpan Depression, presents the contents of organic matter, the distribution of low-carbon fatty acids and the contents of aromatic hydrocarbons as well as their principal ultraviolet absorption spectral and fluorescence spectral characteristics in oilfield waters from different oil/gas-bearing areas. The oil/gas reservoirs in this depression are classified in terms of their conserving conditions. In addition, the paper also discusses the chemical characteristics of oilfield waters from different types of oil/gas reservoirs with an emphasis on the characteristics of their localization in the γ_Na/γCa-γNa/γ_Cl correction diagram. On this basis it is attempted to expound the fundamental geochemical characteristics of oilfield waters from the Turpan Depression and their geological significance.This paper, based on the fundamental inorganic chemical and organic geochemical characteristics of oilfield waters from the Turpan Depression, presents the contents of organic matter, the distribution of low-carbon fatty acids and the contents of aromatic hydrocarbons as well as their principal ultraviolet absorption spectral and fluorescence spectral characteristics in oilfield waters from different oil/gas-bearing areas.
