摘要
探讨了３种离子构型［Ａ（Ⅰ）Ｂ（Ⅰ），Ａ（Ⅰ）２Ｂ（Ⅱ）和Ａ（Ⅱ）Ｂ（Ⅰ）２型］无机盐溶液的密度计算方法。当温度一定时，上述３种离子构型的无机盐溶液的密度与其盐与水质量比（ｍ）均成简单的线性关系，而且，构型相同的盐，其溶液的密度极为相近（温度、浓度相同）。建立了包含温度ｔ和质量比ｍ变量的盐溶液的密度方程，得出了油气田地层水密度的计算方法。
The density of the solutions for three types of inorganic salts, which are of ion structures of A(Ⅰ)B(Ⅰ),A(Ⅰ) 2B(Ⅱ),A(Ⅱ)B(Ⅰ) 2, has been discussed. According to investigations, a kind of simple linear relationship, the density of the solutions vs. mass concertration of salts(g/kg H_2O),has been found. When temperature and salinity are fixed, the density of the solutions is approximately equal to these salts of the same ion structure. Based on these findings, a general equation on the density of the solution, which contains the variables temperature( t ) and mass concentration of salts( m ),has been established. These equations make it possible to calculate the density of formation water of oil or gas field.
