摘　　要：为了研究大庆长垣西部地区第四系白土山组含水层、第三系泰康组含水层的溶解性总固体(TDS)与含水层的电性特征之间的关系,利用研究区的电阻率(Rt)和自然电位(SP)测井资料,通过数值模拟方法建立TDS与Rt、SP之间的关系模型。当第四系白土山组含水层Rt>46Ω.m时,第三系泰康组含水层Rt>45Ω.m时,该层水质可达到TDS<1000mg/L;当第四系白土山组含水层及第三系泰康组含水层静自然电位(SSP)>17mV时,该层水质可达到TDS<1000mg/L;利用建立好的模型对研究区实际井的第四系白土山组含水层及第三系泰康组含水层TDS进行预测,结果误差均小于10%,预测效果较好。研究结果为评价大庆长垣西部地区的地下水水质和圈定具体的布井方位提供了依据,提高了地下饮用水的开采效率。In order to study the relationship between total dissolved solids （TDS） and electrical characteristics of aquifers of Quaternary Baitushan formation and tertiary Taikang formation in Western Daqing placanticline, taking the resistivity （Rt） and spontaneous potential （SP） logging data in the study area , through numerical simulation method to establish the model of relationship among TDS, R,, SP. When Rs 〉46Ω· m in the aquifer of Quaternary Baitushan formation, and R, 〉45Ω· m in the aquifer of tertiary Taikang formation, TDS of water quality can be less than 1000mg/L; when SSP 〉 17mV in the aquifers of quaternary Baitushan formation and tertiary Taikang formation, TDS of water quality can be less than 1000mg/L; The actual well data can be predicted by using the established model, the result errors are all less than 10% , the effect of prediction is quite good. These results provide the basis for evaluating groundwater quality in Western Daqing placanticline and identifying concrete locality of well spacing, and improve the recovery efficiency of underground drinking water.
