摘要
开展地热监测是地热资源开发利用中的一项重要的基础工作,也是了解区域地热资源动态变化的重要手段。常规地热开采监测采用在开采井和回灌井里安装监测设备,获取地热开采和回灌时水温、流量、井口压力、水位、水质等动态参数信息。受开采井和回灌井成井井径、抽水设备直径、法兰盘直径、提泵、放泵、回扬等多种因素的影响,易造成监测设备安装困难及存在损坏可能和风险,不能获取稳定长期监测资料,同时获取的监测数据存在误差。本文根据多年监测实践,探索提出区域地热开采分类监测方法,用户负责实施地热开采和回灌时对水量、水温、水质等监测和传输,管理部门负责通过专用地热监测井监测获取区域水位、水温和水质等信息,二者各负其责,形成互补,可以获得长期、稳定、准确的地热水位、水温、水量和水质监测数据,为地热管理提供有效监测数据。
Carrying out geothermal monitoring is an important basic work in the development and utilization of geothermal resources.and it is also an important means to understand the dynamic changes of regional geothermal resources。Conventional geothermal mining monitoring uses monitoring equipment installed in mining wells and recharge wells to obtain dynamic parameter information such as water temperature,flow rate,wellhead pressure,water level,and water quality during geothermal mining and recharge.Affected by various factors,such as the well diameter of the production well and the recharge well,the diameter of the pumping equipment,the diameter of the flange,the pump,the pump,the backup and other factors,it is easy to cause difficulties in the installation of the monitoring equipment and the possibility of damage and risk,which cannot obtain stable longterm monitoring data,and the obtained monitoring data have errors.Based on years of monitoring practice,classified monitoring methods for regional geothermal exploitation has been put forward.Users are responsible for monitoring and transmitting water volume,water temperature and water quality during geothermal exploitation and reinjection.The management department is responsible for obtaining regional water level,water temperature,water quality and other information through monitoring of special geothermal monitoring wells.Both of them have their own responsibilities and complement each other.They can obtain longterm,stable and accurate geothermal water level,water temperature,water volume and water quality monitoring data,Provide effective monitoring data for geothermal management.
