地热系统温标的建立与应用

Research on Systematic Geothermometer: A Case Study

通过探析传统地球化学温标的弊端和误差机理基础上，根据反应平衡常数的温度函数，以湛江地热田为例，计算了不同参考温度下热储层中热流体各存在组分的活度，并系统考察了地热系统中较多种类的矿物与相应热水溶液间的饱和平衡情况，提出了地热系统温标的建立原理与计算方法，估算了湛江地热田深部热储平衡温度．

A new systematic geothermometer and its algorithm, with the drawback and error mechanism associated with conventional geothermometers, have been presented, based on the equilibrium constants of temperature-dependent reactions. Taken as a pilot, Zhanjiang geothermal field has been explored with the activities of aqueous species in the reservoir and the saturation indexes of given typicaly hydrothermal mineral assemblages at any reference temperature, and the deep reservoir equilibrium temperature been estimated.
