胜利油田陆上采油区浅层地下水与土壤有机污染特征研究

Organic Pollution Characteristics of Shallow Underground Water and Soil in Overland Oil-producing Region of the Shengli Oilfield

本文在对胜利油田陆上采油区水文地质条件和污染源现状分析的基础上,对浅层地下水和包气带土壤进行了样品采集、污染物组分测试及污染程度研究,分析研究结果表明:胜利油田陆上采油区浅层地下水和土壤已普遍受有机物污染并形成多个有机污染区,检出的有机污染物达16种之多,个别有机物含量还很高。浅层地下水污染程度受到油田采油井数量、采油年限及相关石油化工工业布局的控制。

Based on overland hydrogeological condition and pollution situation of the Shengli oilfield,the authors studied the components and pollution extent of organic pollutants in shallow underground water and soil.The result shows that the shallow underground water and soil have been subjected to pollution by organic pollutants and formed many shallow underground water contaminated areas.It is revealed that organic pollutants have 16 kinds of species,among which one or two species are of fairly high content.The extent of the contamination is controlled by the number of oil-mining wells,oil extraction years and relevant layout of petroleum and chemical industry.
