井间ERT监测数据远程传输与数据处理平台设计与开发

针对CO2地质封存过程中井间ERT监测数据处理的需求设计并开发了监测数据综合处理平台。采用4G网络实现了监测数据从现场到监控中心的远程传输，利用MySQL开发了存储监测数据信息和用户信息的数据库，基于有限元法和线性反投影法实现了井间ERT图像重建算法，基于B/S架构和MVC设计模式开发了Web软件。该平台具有监测数据远程传输模块、数据存储模块、基于井间ERT的CO2饱和度成像模块、账户管理模块和CO2封存状态显示模块，可实现监测数据自动远程传输、存储、处理、展示等功能，远程用户登录该平台可对地质封存过程中CO2运移状态进行动态实时监测和历史状态查询。实验室内模拟测试结果表明了各功能模块均可正常运行，从而验证了所开发数据处理平台的可用性。

Design and Development of Data Remote Transmission and Processing Platform for Cross-hole ERT Monitoring

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.
