原油定量荧光图谱分类方法及软件系统研究

采用CNPC“九五”深井测试课题中新研制的PDQFL-1型定量荧光录井仪所测得的定量荧光图谱数据,利用一套数学分类方法,研制开发了原油定量荧光图谱分类软件系统,实现了对油样、含油岩样荧光图谱的预处理、分类建模及自动精细分类处理。利用该软件系统,对西部某油田的岩屑原油定量荧光图谱进行了实际分类处理,验判率高达93%,分析结果科学合理、准确可靠,该软件功能完善、使用方便。为将来进一步深入开展油类和油源对比分析奠定了基础。

QUANTITATIVE CLASSIFICATION METHOD OF CRUDE OIL FLUORESCENCE SPECTRUM AND THE SOFTWARE SYSTEM

In present paper,on the basis of fluorescence spectrum data acquired by recently developed quantitative fluorescence logging instrument (PDQFL-1) and a scienti fic mathematic classification method,the user application software of Quantitati ve Classification System of Crude Oil Fluorescence Spectrum was programmed to re alize the functions of preprocessing,modeling and automatically accurate classif ication for fluorescence spectra of oil and oil-contained rocks.The software wa s practically used to analyze fluorescence spectra of oils in cuttings of one oi lfield in Western China and the verifying ratio is up to 93%.The scientific,rati onal,accurate and reliable analysis results,combined with the advanced functions and convenience of the software,established a solid foundation for further thor ough comparison of the kind and resource of crude oils.
