摘要
在地热系统中,地热温标通常被用来评价地下热储温度,但是如果作为地热温标的化学组分在热储内部没有达到平衡,则估算出的热储温度往往与实际温度相差很远。本文以平顶山八矿地下热水为例,通过Na-K-Mg三角图及以WATCH程序等建立起来的多矿物平衡图在地热系统中的运用,对地热系统中矿物和流体的化学平衡做出了定量和定性的判断,从而为地热温标的选取提供依据。
The geothermometer is usually used to calculate the deep temperatures of geothermal reservoirs in the geothermal system, but if the chemistry component is not balanceable in the geothermal reserviors, the equilibrium temperature of the deep reservior estimated by the geothermometer is not true. Taking thermal groundwater of the eighth coal mine in Pingdingshan for example, both the Na - K - Ca diagram and the lg (Q/K) figure are employed to exam the mineral- fluid equilibrium state qualitatively and quantificationally, which may lay a theoretical foundation for the choice and application of geotherrnometers.
