| 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 additon,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 γNa/γCa-γN a/γCl 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.

| Abstract: | 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 γNa/γCa-γNa/γCl 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. |
