摘　　要：深层富矿卤水是一种重要的矿产资源,卤水层的矿化度是评价卤水品位和开展卤水试水及采卤重要的参数,而卤水层矿化度的计算一直是一个难题。文章推导了地层水电阻率法和中子寿命测井法2种利用测井资料计算矿化度的方法,分别适应于低矿化度和高矿化度卤水,应用这2种方法对江汉盆地潜江凹陷潜江组深层卤水矿化度进行了计算,取得了良好的效果。The highly-mineralized brine of deep zone is a kind of important mineral resources, the salinity of brine for- mations is an important parameter of brine grade evaluation, brine testing and brine mining, and the salinity cal- culation of brine formations has always been a difficult problem. In this paper, the authors used logging data to derive two calculation methods of salinity, i.e., formation water resistivity technique and neutron lifetime tech- nique, respectively, which are suitable for brine with low salinity and high salinity. The authors used these two methods to calculate the deep brine salinity of Qianjiang Formation in the Qianjiang sag of Jianghan basin and achieved good effect.
