摘  要：
以不同开采年限的新老井场为研究对象,以未污染的苇田作为对照,开展了辽河油田土壤石油烃垂直分布特征研究。结果表明,由于含盐泥浆、含油废水和残油渣油泥等在井场开发过程中进入土壤,使井场土壤石油总烃含量(TPHs)显著高于对照,且老井场的污染程度重于新井场。新老井场污染土壤均表现为土壤TPHs含量随剖面深度增加而降低的趋势。

摘  要：
Vertical distribution of the total petroleum hydrocarbons (TPHs) in petroleum-contaminated soil was studied in Liaohe Oilfield. Three sampling sites including new oil-well site (6-year, exploited in 2001), old oil-well site (35-year, exploited in 1972) and reedfield (0-year, unexploited) were selected. The oil-well sites had received slurry, crude oil and wastewater during their exploitations. The results showed that the contents of soil TPHs were significantly higher at the two oil-well sites than that at the reedfield. And their contents were higher at the old oil-well site than that at the new one. The contents of TPHs decreased with decreasing soil depth.
