title: [Preliminary approach to environmental risk assessment of drainage projects during oilfield exploitation in Daqing].
abstract: 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 coefficients, 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.
