main peak

Based on the spectra analysis of samples from different block and different formations of Jiangsu oilfield, the most high peak wave-length, the fluorescence class and the oil-nature index are withdrawed as characteristic values.

在室内实验和现场分析的基础上 ,文章对江苏油田不同断块、不同层位的储集层中不同性质的原油进行定量荧光分析 ,将荧光谱图中主峰波长、主峰荧光强度、油性指数确定为荧光谱图特征值。
