摘　　要：菏泽断裂北部鄄城地热田地热资源丰富,探究区域地热成因机制对菏泽断裂北部地区的地热资源开发利用和经济发展具有重要意义。本文通过对采集的样品进行水文地球化学、气体及其同位素测试分析,结果显示,鄄城地热田地热水水化学类型主要以SO_(4)·HCO_(3)·Cl-Ca·Na、SO_(4)·HCO_(3)Ca·Na和SO_(4)Ca·Na型为主;鄄城地热田呈现出从补给区的浅循环-开放式岩溶地下水流系统(Ⅰ),至径流区的中循环—半开放式岩溶地热水流系统(Ⅱ),再至排泄滞留区的深循环—弱开放式岩溶地热水流系统(Ⅲ)的演化路径。热源以壳源为主,属典型的中低温传导型地热系统。Juancheng geothermal field in the northern of Heze fault is rich in geothermal resources.It is of great significance to explore the formation mechanism of regional geothermal resources for the development and utilization of geothermal resources and economic development in the northern part of Heze fault.In this paper,the collected samples have been analyzed by hydrogeochemistry,gas and isotope tests.It is showed that hydrochemical types of geothermal water in Juancheng geothermal field are mainly SO_(4)·HCO_(3)·Cl-Ca·Na,SO_(4)·HCO_(3)Ca·Na and SO_(4)Ca·Na.Juancheng geothermal field shows the evolution path from the shallow circulation open karst groundwater flow system(Ⅰ)in the recharge area,to the middle circulation semi open karst geothermal water flow system(Ⅱ)in the runoff area,and then to the deep circulation weak open karst geothermal water flow system(Ⅲ)in the discharge retention area.The heat source is mainly shell source,which is a typical medium low temperature conduction geothermal system.
