地热系统中矿物-流体化学平衡的计算

Calculation of the Fluid-rock Equilibrium State in the Geothermal System

在热勘探过程中 ,建立在水 -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。本文采用多矿物平衡图解法和Na -K -Mg三角图解法 ,研究西藏高温及江西中低温地热流体的平衡状态 ,从而为地热温标的选择提供了理论依据。

The geothermometer is often used to calculate the deep temperatures of geothermal reservoirs on the basis of water rock equilibrium in the exploration of the geothermal resources.The log( Q/K ) diagram and the Na-K-Mg triangular diagram are used to study the equilibrium state of thermal fluids in this paper, which may lay a theoretical foundation for optimixation of the geothermometers.\;
