卡尔费休库伦法在岩石含水饱和度中的应用

Application of Karl Fischer coulomb in rock water saturation

目前,岩石含水饱和度测定方法主要有干馏减量法、蒸馏法、气相色谱法和卡尔费休库伦法4种。卡尔费休库伦法具有操作简单、速度快、精度高、携带方便等优点。本文着重介绍了卡尔费休库伦法的测量原理,测试方法及测量结果的准确性。

There are four methods for determination of water saturation in rocks ： dry distillation and decrement, distillation,gas chromatography and Karl Fischer coulomb method. Karl Fischer coulomb method has the advantages of simple operation, high speed, high precision, and portability. This article focuses on the measurement principle, test methods and measurement accuracy of Karl Fischer Coulomb method.
