Abstract: Longterm oil exploitation causes quality deterioration of the soil in Shengli Oilfield. However, we know very little about the contamination characteristics of the heavy metals in the soil of oilfields. We discovered that enrichment factors of Cu, Zn, Cd and Ni were 3.44, 5.79, 8.08 and 2.47 and potential pollution risk existed through the sampling and analysis of eight heavy metals (Cu, Zn, Pb, Cd, Cr, Ni, V and Mn) in the soil of Gudao oil region of Shengli Oilfield. Heavy metal speciation analysis results reveal that the speciation distribution of heavy metals are probably affected by oil pollution in the soil.

Key words: soil, heavy metal, oil region, oil pollution, speciation analysis
