摘要
通过测井资料间接求取地层水矿化度或地层水电阻率的方法受诸多因素的影响，致使通过测井资料计算的地层水矿化度或地层水电阻率存在一定误差。为更加准确测定地层水矿化度，尝试利用原始砂岩岩样求取地层水矿化度；介绍了其实验方法、原理及过程，分析了实验数据。由该方法得到的地层水矿化度与实际地层水矿化度基本一致，具有较好的应用效果。
Currently, formation water salinity or formation water resistivity are almost indirectly calculated by logging data. Due to the impact of many factors, the above calculated results have certain errors. In order to more accurately determine formation water salinity, original sandstone samples are used to calculate formation water salinity with experiment method. Introduced are experiment principle and procedure; analyzed are experiment datum. Analysis results show that formation water salinity obtained from experimental method is consistent with actual formation water salinity. The method has better application effect.
