为了对原油中金属元素含量进行分析，利用激光诱导击穿光谱技术分别采用Na光谱的积分强度、峰值强度作定标曲线对高温灼烧后的原油中的Na进行了定量分析。实验中选取NaⅠ588．995nm，Mg Ⅰ383．230nm， Al Ⅰ308．215nm，KⅠ404．414nm，CaⅠ364．441nm，Fe Ⅱ273．955nm作为分析线对原油样品灼烧后的6种元素进行分析，测得其质量分数分别为0．0592，0．0029，0．0212，0．0019，0．0072，0．1686，并得出了定标曲线的线性相关系数及检出限。结果表明，选用积分强度作定标曲线效果更好；激光诱导击穿光谱技术测量结果与X射线荧光光谱技术对Na的测量结果相对误差为6．28％；激光诱导击穿光谱技术可应用于原油中金属元素含量的测量。

In order to analyze the content of metal elements in crude oil, Na in crude oil after thermal process was quantitatively analyzed by calibration curve for integrated intensity and peak intensity of spectrum respectively by using the technology of laser-induced breakdown spectroscopy.6 elements were quantitatively analyzed on the basis of NaⅠ588.995nm, MgⅠ383.230nm, Al Ⅰ308.215nm, KⅠ404.414nm, CaⅠ364.441nm, FeⅡ273.955nm in the experiment.The mass fraction of above 6 elements were 0.0592,0.0029,0.0212,0.0019,0.0072,0.1686 according to calibration curves for element content and integrated intensity, and the linear correlation coefficient and the detection limit of calibration curves were also calculated.It turned out that it is better to choose the integrated intensity for calibration curve.Na is also quantitatively analyzed by using the technology of X-ray fluorescence spectroscope.Compared with the measurement results of laser-induced breakdown spectroscopy and X-ray fluorescence spectroscopy, the relative error is 6.28%.The technology of laser-induced breakdown spectroscopy could be applied to measure the content of metal elements in crude oil.
