油田开发土壤污染环境影响评价方法的研究

以土壤水运动方程和溶质运移方程的联合模型(确定性模型)模拟结果为基础，考虑土壤环境系统内部结构和功能的复杂性以及石油污染物在土壤中化学转化反应的不可完全预知性，同时考虑整个相关的系统因素，引入灰色系统建模方法，分别建立GM(1，4)模型和GM(2，1)模型，对石油类物质在土壤环境中的迁移转化规律进行分析和预测，提出油田开发土壤污染环境影响的定量化评价方法。此方法的提出为油田开发环境影响评价中土壤污染部分的定量性评价提供了一个很好的研究思路。

Methodology for Environmental Impact Assessment in Soil with Petroleum Pollution in Oil Field Exploitation

During process of oil field exploitation and oil production, due to limitation of technology and technique, it is inevitably to yield a great number of contaminations in around soil. The contaminations may mainly contain petroleum pollutants and probably phreatic water and deep ground water. Therefore, how to assess the impact of oil exploitation on soil environment is an important issue in terms of integrated environmental impact assessment. Based on simulated results from the combined equations of soil water movement and solute transportation (available model), and taking account for the complexity of soil inner environment and its function as well as the unpredictability of the contaminations' chemical transformation in soil, we adapts the gray system theory to establish both GM (1,4) and GM (2,1) model, respectively, in this investigation. The model has been indicated to be capable of analyzing and predicting the oil transferring in soil and further proposes the quantitative assessment method for oil pollution in the soil. This method provides many insights into the quantitative soil environmental impact assessment with oil filed exploitation.
