定量荧光录井的影响因素及对策探讨

Discussion about influencing factors and countermeasures of quantitative fluorescence logging

该文针对定量荧光录井过程中出现的同质不同谱、同谱不同质等异常现象,详细客观地分析了原油组分的多样性、荧光物质的复杂性、原油密度与油性指数的关系、荧光淬灭现象、储集层物性等各种可能影响定量荧光录井的因素,提出了油质细分标准、采用积分方法求含油浓度、规范样品分析方法和更新资料处理方法等一些新思路和新方法,对于定量荧光录井的深入发展具有积极的推动作用。

The paper analyzed objectively and in great detail the various factors those are possible to affect quantitative fluorescence logging, such as diversity of oil component, complexity of fluorescence material, relationship between oil density and oil property index, fluorescence extinguishing phenomenon and reservoir physical property according to abnormal phenomena such as the same quality with different spectrum and the same spectrum with the different quality happening during quantitative fluorescence logging. The authors provided some new thoughts and ways, such as detailed dividing standard for oil quality, getting oil bearing concentration using integral method, specifying sample analyzing way and renewing data processing method, which have active improving effects for deeply developing of quantitative fluorescence logging.
