地下卤水水化学特征及成因探讨

Discussion on hydrochemical characteristics and genesis of underground brine

地下卤水资源丰富,有很高的资源价值和经济价值,可用于军工、化工、电子、制药等领域。为进一步开发利用卤水资源,评价资源的开发利用前景,研究卤水的成因、演化、物源等信息,从地下卤水化学特征角度研究了卤水成因。提出根据地下水中的钠氯系数、脱硫系数、钙镁系数、钠钙系数、溴氯系数、氯钾系数等来分别分析推测地下卤水成因;根据(Na+Ca)/Cl的物质的量浓度比值与其他水体相比来判断成因类型;根据c(Na)/c(Cl)的物质的量浓度比值来判断卤水蒸发浓缩和岩盐溶解淋氯作用,从而判断卤水形成过程;根据ρCl/ρBr来判断卤水的物源。

Underground brine resource is rich,has a high resource value and economic value,and can be used in militaryindustry, chemical industry, electronics, pharmaceutical and other fields. For further development and utilization of brineresource, evaluation of development and utilization prospects, of the brine resource research into the cause, evolution andsource information of the brine, the brine was discussed from the viewpoint of underground brine chemical characteristics.According to the sodium chloride coefficient,desulfurization coefficient,calcium magnesium coefficient, sodium andcalcium coefficient, bromine chloride coefficient a and potassium chloride coefficient in groundwater, the genessis of theunderground brine was analyzed and speculeted; according to the mole concentration ratio （Na ＋ Ca）/and C1 compared withother water bodies to genetic types were determined analysized ; according to the mole concentration ratio cNa/cC1 judgingNa and Cl,the evaporation concentration and leaching effect of chlorine salt dissolving,formation were judged in order tobrine determined the formation procecs of the brines; according to the ratio of the density of C1 and Br,the sediment sourceof the brine were determined.
