CO2 flooding and sequestration technology can significantly improve crude oil recovery rates while enge.However,the oil displaceabling large-scale CO2 flooding and sequestration process is accompanied by various CO2 leakage risks.In response to the lack of previous CO2 leakage risk management systems,especially the absence of systems based on online monitoring that support dynamic risk management,research has been conducted on the construction of a CO2 flooding and sequestration leakage risk management system.Based on the construction of CO2 flooding and storage leakage risk management system,a dynamic CO2 leakage risk management system integrating multi-environment real-time risk identification and assessment,multi-space risk prediction,multi-level risk early warning and whole process risk control was developed and applied to the CO2 flooding and storage demonstration project of Yanchang Petroleum in Ordos Basin.Case studies demonstrate that the developed CO2 leakage risk management system can dynamically identify various leakage risks throughout the CO2 flooding and sequestration process across all spaces,effectively supporting the dynamic management of leakage risks.This provides comprehensive and timely safety assurance for CO2 flooding and sequestration projects,ensuring that potential risks are managed and mitigated effectively to maintain the integrity and success of these projects.
