摘要: 传统的二维发射光谱所能直接测定的原油质量浓度范围很有限,一般为0~4×10-2g/L. 针对这种情况提出了同步荧光光谱分段函数确定原油质量浓度的新方法,该方法适用于质量浓度在1.22×10-4~3.0 g/L 的原油样品,极大地扩展了可直接测定的原油质量浓度的范围。所拟合的原油质量浓度函数形式简单,计算量小,准确率较高。

Abstract: The conventional two-dimensional emission spectrum shows a limited range of crude mass concentration that is directly determined from 0 to 4×10-2g/L. This paper proposes a new method suitable for ranges from 1.22×10-4g/L to 3.0 g/L by piecewise function of synchronous fluorescence spectrum to determine the crude mass concentration. The mass concentration function forms matched by this method are simple, with not so much calculation, but high accuracy.

Key words: synchronous fluorescence spectroscopy (SFS), matching, fluorescence logging, crude oil, mass concentration
