【摘要】 洒落石油对地面生态（土壤、包气带）的污染主要分布在井下作业频繁与窃油现象严重的采油井井场内。油污染物在包气带中运移，并受油污染浓度大小的控制，当石油污染物的浓度大于近似残余饱和度，污染物向下迁移，对地下水产生污染。油污染处理最为妥当的方法是生物处理技术，可进行推广使用。更多还原

【Abstract】 Pollution of scattered oil to ground ecology appears mainly in the oilfields where frequent oil extraction and serious oil stealing happen. Oil pollutants are transferred in atmosphere and controlled by its density. When its density is higher than approximate remnant saturation degree, the pollutants move downward to pollute the groundwater. The proper method to oil pollution is by means of biotechnology, which can be widespread.更多还原
