摘要：

根据我国地热利用的实际经验，指出传统使用的雷兹诺（Ryznar）指数在判断地热水的结垢趋势时，有一定局限性。在一定条件下，采用腊森（Larson）指数，才能得出正确结果，这一结论已被广泛用于地热井的水型判断。

Abstract:

Based on the actual experiences of geothermal utilization in China,the authors pointed out that the traditional Ryznar Index has many limitations when it was used to judge the scaling tendency of geothermal water. In some cases, Larson Index should be adopted in order to get correct results. This conclusion has been applied widely to judge the type of geothermal water.

Key words: geo thermal water, scale tendency, Ryznar Index, Larson Index
