摘要
Na^+, Ca^+ and Mg^+ are known to be the principal mineralizing cations in oil-field waters.Chemical controls on their activity and concentration are solubility, adsorption capacity and hydration which are dependent on the primary chemical bond parameters, such as ionic potential (Z/L)and dectronegativity (x). This paper aims at expounding the regularities governing the quantitative distribution of Na, Ca, and Mg in nil-field waters in terms of the variation of φ(Z/L, x). Our studies have shown that the log concentrations of Na, Ca and Mg in oil-field water shave a linear correlation ,vith their ionic potential and dectronegativity. Therefore, the concentrations of these cations must follow the φ(Z/L, x) regularity which has found ,vide application in the following aspects: (1) to define various types of nil-field water; (2) to define the distribution of oil-field and non-oil-field waters; and (3) to define the boundaries of hydrochemical vertical zonation.

Our studies have shown that the log concentrations of Na, Ca and Mg in oil-field watershave a linear correlation with their ionic potential and electronegativity. Therefore, the con-centrations of these cations must follow the φ(Z/L, x) regularity which has found wide ap-plication in the following aspects: (1) to define various types of oil-field water; (2) to de-fine the distribution of oil-field and non-oil-field waters; and (3) to define the boundariesof hydrochemical vertical zonation.
