摘要
在地热资源勘探过程中，建立在水一岩平衡基础上的地热温标方法常被用来评价地下热储温度。但在某些情况下，作为地热温标的化学组分并没有真正与热储内部的矿物达到平衡，本文采用ｌｏｇ（Ｑ／Ｋ）图、不同参考温度下的平衡状态判定和Ｎａ－Ｋ－Ｍｇ三角国的方法来研究热流体的平衡状态，为地热温标的优化奠定了理论基础。
The geothermometer is often used to calculate the deep temperatures of geothermal reservoirs on the basis of water-rock equilibrium in the exploration of geothermal resources. In some cases, however, the chemical components as geothermometers are not in real equilibrium with the minerals in the reservoir. The log (Q K) diagram, the judgement of the equilibrium states at different reference temperatures, and the NaK-Mg triangular diagram are used to study the equilibrium state of thermal fluids in this paper, which may lay a theoretical foundation for optimization of the geothermometers.
