摘　　要：地下水脆弱性能够反映地下水系统遭受污染的可能性。文章结合某油田地质及水文地质条件,基于DRASTIC评价方法构建DRASTIC指标评价体系,进行地下水脆弱性能评价。结果表明,研究区地下水脆弱性中等区域分布面积最广,其后依次为地下水脆弱性较高区域、地下水脆弱性较低区域、脆弱性高区域。研究成果可为油田开采过程中地下水保护及污染防治提供科学依据。Groundwater vulnerability can reflect the possibility of groundwater system being polluted. Combining with the geological and hydrogeological conditions of an oilfield, this paper constructs a DRASTIC index evaluation system based on the DRASTIC evaluation method to evaluate the vulnerability performance of groundwater. The results show that the medium groundwater vulnerability region in the study area has the largest distribution area, followed by the higher groundwater vulnerability region, the lower groundwater vulnerability region, and the high vulnerability region. The research results can provide a scientific basis for groundwater protection and pollution prevention in the process of oilfield exploitation.
