Study on Continuous Monitoring Technology for CO2 Concentration of Shale Oil Associated Natural Gas
A large amount of CO2 injected during shale oil well fracturing will be separated with the production of crude oil and natural gas.To accurately understand the CO2 output,a continuous CO2 concentration monitoring device based on infrared gas analysis method has been developed.The core module of the monitoring device,as well as the technical parameters and performance of each component,are introduced.In on-site application,real time and continuous monitoring of CO2 concentration in shale oil associated gas has been achieved.The monitoring device is of the characteristics of fast detection,accurate results,and high efficiency.Manual labor intensity is significantly reduced.The data accuracy performance meets the requirements of data acquisition and production management.
