地热系统气体地球化学研究进展

RESEARCH ADVANCES IN GAS GEOCHEMISTRY OF GEOTHERMAL SYSTEMS

地热系统气体地球化学是迅速发展起来的一个新领域。本文综述了有关地热田气体组份来源的研究工作，回顾了气体地热温度计的阶段性发展，提出了气体地热温度计的分类，概述了地热系统气－水－岩石体系化学热力学模拟的意义，报道了应用气体地球化学研究和开发地热田的进展。

Gas geochemistry of geothermal systems is a new developing fields. This paper intreduced thestudies on gas origins in geothermal fields ,reviewed the progresses of gas geothermometers ,suggestedthe classification of existed gas geothermometers. It is discussed the significance of simulation on gas-water-rock in geothermal systems. Advances on gas geochemistry applied in geothermal exploita-tion are reported also。
