Evaluation of specific vulnerability of a groundwater system in an oilfield
摘要
Abstract
Considering hydrogeological conditions and main oil pollutant properties in typical oilfields of China, a new model named DORKI was proposed for specific vulnerability assessment of groundwater in an oilfield, based on the widely used DRASTIC model.In this new model, three evaluation factors including depth to water table, net recharged water amount and media of vadose zone are selected from DRASTIC.Two additional factors are organic content of soil and soil sorption coefficient.The score of the additional factors was established based on relevant data and the weights of the five factors were determined according to ninedemarcation method of the analytic hierarchy process (AHP).Application of the model to evaluate groundwater situation in an oilfield district shows that the DORKI can reasonably reflect the effect of the additional factors in the evaluation.关键词
