大庆地区油田开发排水工程环境风险评价初探

Preliminary approach to environmental risk assessment of drainage projects during oilfield exploitation in Daqing.

利用定性分析的方法 ,对大庆地区永乐油田永 5转油站地区不同设计排水方案进行环境风险因素识别和危害环境预测 ,在此基础上 ,运用模糊综合评价法 ,建立相应的环境风险模糊指数 ,确定危害环境系数 ,最后得出环境风险模糊评价指数 ,表征各方案风险相对大小 ,提出针对优选方案环境风险管理的措施 .

A qualitative analysis was made to assess the environmental risk and its impact of alternative drainage projects around Yong-5 oil-transport station at Yongle oilfield in Daqing.On the basis of this ,a method of fuzzy comprehensive assessment was applied to set up corresponding indexes,to determine hazard environmental coefficiens,and to calculate the environmental risk fuzzy assessment indexes which reflect the relative risk degrees of alternative drainage projects.The measures on environmental risk management were proposed according to the priority of alternative projects.
