Abstract:A comprehensive platform for data processing was designed and developed to meet the requirements of dealing with cross-hole ERT monitoring data during CO2 geological storage. The remote transmission of monitoring data from the field site to the monitoring center was achieved using a 4G network. A database was developed using MySQL to store the information of the monitoring data and users. The cross-hole ERT image reconstruction algorithm was implemented based on finite element method and linear back projection method. A Web-based software was developed based on B/S architecture and MVC design mode. The developed data-processing platform include the following functional modules, i.e., the monitoring-data remote transmission module, data storage module, CO2 saturation imaging module based on cross-hole ERT, account management module, and CO2 storage status displaying module. The functions such as automatic remote transmission, storage, processing and displaying of monitoring data can be achieved. In addition, remote users can log into the platform to dynamically monitor and query the historical status of CO2 migration during its geological storage process. The test results have shown that all the functional modules can operate normally, which verifies the usability of the developed data processing platform.
