摘要
国内已初步建立重点地区及区域的地下水在线监测网络,实时对地下水动态等进行在线监测,其监测指标主要针对温度、电导率、pH值等基本水质因子,但对于现有气田回注井,地下水环境监测的重点是气田回注水中的氯离子(Cl-)、VOCs(石油类)、硫化物等特征因子是否存在泄露,现有监测主要采取每月一次现场地下水采样送样,实验室分析,耗费人力物力.针对气矿监测井中的地下水动态监测,研发一种快速便携式气田水回注地下水环境在线监测仪器,重点解决特征水质因子的野外现场的在线监测与分析,实现提高工作效率目标.
Abstract
An online groundwater monitoring network has been initially established in key areas and regions to monitor groundwater dynamics in real time in China.The monitoring indicators are mainly for basic water quality factors such as temperature,electrical conductivity and pH value.However,for existing gas field reinjection Wells,the focus of groundwater environment monitoring is whether there is leakage of characteristic factors[chloride ion(Cl-),VOCs(petroleum),sulfide]in gas field reinjection water.The existing monitoring mainly adopts on-site groundwater sampling and sample delivery once a month,and laboratory analysis,which costs manpower and material resources.Aiming at the dynamic monitoring of groundwater in the gas mine monitoring well,a fast portable groundwater environment monitoring instrument for gas field water reinjection was developed,focusing on the online monitoring and analysis of characteristic water quality factors in the field,so as to achieve the goal of improving work efficiency.
