摘要
为研究油田开采对环境造成的影响,以大庆地区正在开采和停止开采的油井为研究目标,采集油井周围不同距离和层次的土壤,检测其重金属(Pb、Cd、Hg、As)含量。结果表明,在同一水平距离,正在开采的油井周围土壤重金属含量高于停止开采的油井周围;在某一水平距离处,随着土壤层次的加深,土壤中Pb的含量逐渐降低;而Cd、Hg、As含量基本呈现先降低后增加的趋势。
The exploring and disused oil-well as research target in Daqing to study the effect of exploring oil-well on the environment, soil was collected in different level grads and soil layer, and the heavy metal Pb, Cd, Hg and As content were detected around oil-well, the result shows that heavy metal content around the exploring oil-well were higher than disused oil-well in the same level distance, the content Pb, Cd,Hg and As gradually reduce in a certain level distance along with the gradually deep of soil layer in both exploring and disused oil-well.
