摘　　要：在天津市西北部应急供水水文地质详查勘探区,使用PSJ系列数字测井仪对勘探区三条勘探线上9眼探采结合井进行了标准测井,并按照解释原则进行曲线综合对比确定地层岩性及顶、底界限的划分,在此基础上解释出含水砂层的位置和厚度。通过对钻探取心以及测井工作所获得的水文地质参数进行分析得知:该勘探区的不同地段,100m深度内富水性有较大的差异,含水层以细中砂为主,其渗透性总体上北部要好于南部,西部要好于东部。In the emergency water supply hydrogeological preliminary exploration area,northwestern Tianjin,the PSJ series digital logger has used to carry out standard well logging in 9 exploration-production wells located on 3 exploration lines.Based on interpretation principle has carried out logging traces integrated correlation to determine strata lithology and roof and floor limitation,and interpreted water-bearing sand beds location and thickness on this basis.After analyzed hydrogeological parameters acquired from drilling coring and well logging,inquired out that in different sectors of the exploration area,above 100m depth,the water yield properties exist major differences.Aquifers are mainly fine to medium grained sands,as a whole,the permeability in the northern part is better than southern part,western part better than eastern part.
