汤市地热流体化学成因分析

摘要

汤市地热资源丰富，具有流量大、温度高、无色的特点，3个自溢泉是当地居民主要的生活用水来源，也是当地主要的旅游开发资源。在分析 ZK01，ZK02，QK02，QK03和 QK04的基础上对汤市地热流体化学成因和循环条件进行研究分析，确定地热成因、热储条件等主要是由于断层 F 和 F1的相互作用形成，水化学主要是纳、钙、重碳酸根离子为主，偏弱酸性的低矿化度水。%Tangshi area has enriched geothermal resources,characterized by large quantity of flow,high temperature,and colorless.There have three fountains,which are a major source of domestic water as well as tourism development.Based on the analysis of borehole ZK01,ZK02,QK02,QK03,and QK04,this paper analyzes the chemical causes and the circulation conditions.It shows that the cause of geothermal and the thermal storage conditions are mainly affected by the mutual interaction between fault F and F1. The hydrochemistry is mainly Na,Ca,and bicarbonate ions,so the water is week -acid and low -salinity.
