Description

Technical field [0001] The invention relates to a carbon dioxide remote wireless real-time monitoring system, in particular to a carbon dioxide geological storage real-time monitoring system and method based on a wireless sensor network. Background technique [0002] Carbon dioxide capture and storage (CO 2 Capture and Storage (CCS) can capture carbon dioxide produced by fixed point sources (such as power stations and steel mills) and store them in the ocean or relatively closed geological structures for a long time, thereby preventing or significantly reducing the anthropogenic emissions of carbon dioxide into the atmosphere . After geological storage, carbon dioxide must be maintained in a liquid state by the pressure of the formation, otherwise it will volatilize into the air. At present, the methods and technologies for leakage monitoring and prediction of underground carbon dioxide storage tanks are not yet mature. Once storage problems occur and a large amount of carbon d...

Problems solved by technology

However, the method designed for infrared CO 2 Monitors can only rely on manual reading of monitoring data, it is difficult to achieve remote data transmission and poor real-time monitoring

[0008] The above methods either design carbon dioxide geological storage leakage monitoring instruments, or focus on subtracting background interference concentration leakage monitoring methods, or use soil CO 2 Content and isotope monitoring gas leakage measurement methods caused by drilling, have not carried out the specific design and realization of the wireless ad hoc network and wireless transmission scheme between monitoring instruments, therefore, there is an urgent need for a method that can make full use of the existing carbon dioxide geological storage injection wells Monitoring and distribution of monitoring wells, taking into account the monitoring needs of large-scale discrete and small-scale dense distribution of monitoring wells, monitoring with simple structure, flexible point layout, remote monitoring, wireless transmission, real-time display, low cost and low power consumption Program
