胜利油田土壤污染范围分析及复垦技术研究

通过实地采样和室内分析,对石油污染土壤的范围进行了研究。对土壤含油量指标与距离进行指数函数的拟合,经计算得到距油井周边160m范围内是受石油污染的区域,160m之外的土壤含油量可以认为低于临界值。并根据该数值,对东营市胜利油田10个采油厂的废弃工矿区进行计算,周边污染土壤可达到2025.67hm2;此外,还对石油污染土壤的复垦技术进行了探讨;可以为东营市及其他类似区域土地整治过程中污染土壤的治理提供参考。

Study on Soil Scope Polluted by Oil and Reclamation Technology in Shengli Oilfield

In this paper, through field sampling and indoor analysis, the soil scope which have been polluted by oil has been studied. Based on the fitting function of oil content in sampling spots and the distance to the oil well, the oil pollution area has been calculated. As showed by the result, the region within the scope of 160m around the oil well is oil polluted area, while the region beyond the scope of 160m can be regarded as less than critical value. Based on this result, 10 abondanded industrial and mining waste oil plants of Shengli Oilfield in Dongying City have been calculated. The surrounding polluted soil can reach 2025.67hm2. Polluted land reclamation technology has been studied in this paper as well, which can provide some references for land reclamation work in Dongying city and other places.
