摘　　要：采用氨化木质素处理油田污泥,通过处理前后污泥中钙离子含量、污泥疏松度、含水率的变化对氨化木质素处理效果进行评价。评价结果表明,氨化木质素处理后的油田污泥中可被置换的钙含量减少,络合钙含量增加;污泥疏松度及显微结构分析均表明,氨化木质素能有效改善油田污泥疏松度;氨化木质素可在很大程度上增加油田污泥吸水率。The ammoniated lignin was applied for treatment of oilfield sludge.The treatment performance was evaluated by detecting the calcium content,the loosen degree and water content of the treated oilfield sludge.Results showed that ammoniated lignin presented perfect performance in oilfield sludge treatment;it could reduce the content of replaceable Ca2＋ and increase the content of complex calcium in oilfield sludge.Ammoniated lignin could also rise the loosen degree and water content of oilfield sludge significantly.
