摘要
针对原油中微量金属元素含量低、富集难、分析难的问题,研发了微量金属元素富集技术和分析技术,建立了微量金属元素检测方法.实验结果表明：检出种类多,可同时检出原油中26种微量金属元素;检出限低,最低可达1μg/L;稳定性好,平均标准偏差为4.7％;准确度高,加标回收率为92％ ～ 105％.在勘探领域应用原油中微量金属元素特征,可判别原油来源和指示原油运移方向。
In the light of the problems of the low content,hard enrichment and difficult analysis of trace metallic elements in crude oil,the enriching and analyzing technique for the elements is developed,and moreover the corresponding testing methods are established.The experimental results show that so many elements can be detected such as 26 kinds of the trace metallic elements could be found simuhaneously in crude oil; and the detection limit can be very low,the least can reach 1 μg/L; the stability is good,the mean standard deviation is 4.7％ ; the accuracy is high,the marked recovery rate is between 92％ and 105％.In the field of the exploration,the characteristics of the trace metallic elements in the crude oil can judge the origin and indicate the migration direction of the crude oil.
