针对目前大庆油田工作油井污染现状，对大庆市大同区八井子乡油井附近农田土壤进行采样调查，以了解目前工作中单井附近土壤污染状况，并结合污染现状提出合理性建议；此次采样调查以单口油井为中心，分别以0、20、40和60 m为半径进行取土采样，检测耕地土壤的石油类物质总量。结果表明：横向采样的土壤全部超过国家第一级标准限值，石油类物质总量随着横向距离的增加而降低。某些单井附近耕地土壤已超过国家第二级标准限值，最高超标倍数为13.88倍，处于危险级别，应立即采取措施治理石油污染。

With regard to the current status of contamination caused by oil wells of Daqing Oil Field, soils in the farmland of Bajingzi Village, Datong District, Daqing City nearby the oil field were sampled and investigated for understanding of the situation of soil pollution near single oil well. Furthermore, rational recommendations were proposed regarding the oil pollution. In Bajingzi Village, Datong District, Daqing City, single well in the working state was taken as the centre and soils were sampled at the radius of 0, 20, 40 and 60m respectively from the single well for detection of the total amount of oil pollutants in the farmland. The results showed that the soils sampled horizontally all exceeded the limits of the national class I standard and the total amount of petroleum-based substances decreased with the increase of horizontal distance. The farmland soils near some certain single wells exceeded the limits of the national class II standard, maximally by 13.88 times, so they were in a dangerous level and measures should be taken immediately to control the petroleum contamination.
