摘　　要：以鄂尔多斯盆地乔家洼CCS-EOR项目为例,通过工程活动指标分解及选项设计,形成涵盖油区特征、储盖层特征、工程设计、工程监管4大类20个指标的环境风险可能性判定指标体系,利用问卷调查和专家打分法,界定驱油工程环境风险可能性。结合国内外文献分析,开展项目对空气、土壤和微生物、作物、动物及人群等环境风险受体的影响程度界定,基于界定结果,按照风险评估矩阵,对该工程CO_(2)泄漏环境风险水平的评估结论为低风险,在后期运行过程中应强化风险防范与监测。Taking Qiaojiawa CCS-EOR project in Ordos basin as an example,through the decomposition and option design of engineering activity indicators,an environmental risk possibility judgment index system was formed covering 20 indexes in 4 categories,oil region characteristics,reservoir cover characteristics,engineering design and engineering supervision.The possibility of environmental risk in oil displacement engineering was determined by questionnaires and expert scores.At the same time,combined with domestic and foreign literature,the impact of the project on environmental risk receptors such as air,soil,microorganisms,crops,animals and people were defined.The environmental risk level of CO_(2)leakage of the project was assessed as low risk based on the defined results and the risk assessment matrix.Risk prevention and monitoring should be strengthened in the later operation process.
