| 摘 要： | 以大港原油为研究对象 ,通过加水萃取试验、实沸点蒸馏和氧化铝柱色谱四组份分析及全溶剂法四组份分析对原油中的钙和镍进行了研究 ,发现原油中的钙大部分是非水溶性钙 ,和镍一样主要富集在渣油中。但四组份分析结果表明 ,钙和镍的存在状态具有很大的差异。

| Abstract: | The abundance,water-solubility,distribution characteristics and occurrence modes of calcium and nickel in crude oil of Dagang oilfield were studied by means of water-extraction,true boiling point-distillation,and four group fractions analysis of residue.It is found that the majority of calcium and nickel compounds are insoluble in water and are concentrated in the residue.But the analysis results of four group fractions demonstrate that the occurrence mode of calcium compounds is different from that of nickel-compounds. |
