Study on On-line Monitoring Device for Groundwater Environmental Characteristics and Water Quality Factors of Gas Field Reinjection
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.
