摘　　要：CO_(2)驱油封存技术在提高原油采收率的同时能实现大规模CO_(2)封存。然而,驱油封存过程伴随着多种CO_(2)泄漏风险。针对以往CO_(2)泄漏风险管理系统的缺乏,特别是缺少基于在线监测的管理系统,难以支撑动态的风险管理,研究基于CO_(2)驱油封存泄漏风险管理体系的构建,开发了集成多环境实时风险识别和评估、多空间风险预测、多层级风险预警和全过程风险控制的动态CO_(2)泄漏风险管理系统,并应用于鄂尔多斯盆地延长石油CO_(2)驱油封存示范项目。案例应用研究表明,所开发的CO_(2)泄漏风险管理系统可以全空间动态识别CO_(2)驱油封存过程的各种泄漏风险,有效支撑泄漏风险的动态管理,为CO_(2)驱油封存项目提供全面及时的安全保障。CO_(2) flooding and sequestration technology can significantly improve crude oil recovery rates while enge.However,the oil displaceabling large-scale CO_(2) flooding and sequestration process is accompanied by various CO_(2) leakage risks.In response to the lack of previous CO_(2) 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 CO_(2) flooding and sequestration leakage risk management system.Based on the construction of CO_(2) flooding and storage leakage risk management system,a dynamic CO_(2) 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 CO_(2) flooding and storage demonstration project of Yanchang Petroleum in Ordos Basin.Case studies demonstrate that the developed CO_(2) leakage risk management system can dynamically identify various leakage risks throughout the CO_(2) flooding and sequestration process across all spaces,effectively supporting the dynamic management of leakage risks.This provides comprehensive and timely safety assurance for CO_(2) flooding and sequestration projects,ensuring that potential risks are managed and mitigated effectively to maintain the integrity and success of these projects.
