地热系统中的混合作用及其应用研究

地热系统中冷水和热水的混合作用是一种非常普遍的现象，它伴随在地热流体循环的整个过程之中。研究混合作用，对认识地热水的形成条件及其化学成分的演化规津、对评价地热田的开发潜力等方面都具有非常重要的意义。本文在分析混合地热水的主要标志的基础上，重点探讨了混合作用的水化学效应．最后对冰岛Ｈｒｉｓｅｙ热田的混合作用实例进行了研究。

STUDIES OF MIXING AND ITS APPLICATION IN GEOTHERMAL SYSTEMS

The mixing of cold water and hot water in geothermal systems is a very common phenomenon, and it accompanies the whole circulatory process of geothermal fluids. The studies of mixture are very important tounderstanding the formation condition of hot waters, and evolutionary regulation of hydrochemical components, etc. On the basis of analysing the major symbols of mixed geothermal waters,this paper mainly discusses the hydrochemical effects of mixing and, at last, studies the pratical example of mixing in thermal fieldHrisey, Iceland deeply and carefully.
