摘要
分析了页岩气开采过程中水资源和水环境风险,并在此基础上建立了页岩气开发的水资源水环境风险评价指标体系,具体风险包括水资源量风险、地表水污染风险以及地下水污染风险三大类别。将水资源水环境风险评价指标体系运用于实例,分析了我国四川某页岩气开发项目的水资源水环境风险。结果显示,该页岩气开采项目的整体评价结果为较高风险,其中水资源量风险为低风险,地表水污染风险为较低风险,地下水污染风险为较高风险。
The risks of water resources and water environment in the exploitation process of shale gas are analyzed. On this basis, the risk assessment index system for risks of water resources and water environment in the exploitation process of shale gas is established, specifically including three categories: risk of water resources, risk of surface water pollution and risk of groundwater pollution. Then the proposed assessment system is applied to a case study, and the risks of water resources and water environment of a shale gas project in Sichuan Province of China are investigated. The results show that the overall assessment of the shale gas project is of higher risks, among which the risk of water resources is low, that of surface water pollution is lower, and that of groundwater pollution is higher.
