| 摘 要： | 分析了钻井液添加剂的荧光发射机理及传统荧光评价方法存在的问题 ,在对国内外文献调研和室内研究的基础上建立了一种新的定量荧光评价方法。该评价方法克服了荧光自熄和浓度消光现象 ,避免了人为产生的误差 ,测试结果有效性强 ,特别是对于凝析油、轻质油及荧光发射波长小于 4 0 0nm的钻井液添加剂的荧光评价更为有效。对新、旧评价方法进行了对比 ,结果表明 ,新方法更有利于评价钻井液添加剂及其体系对原油荧光显示的影响程度 ,结果更为准确、可靠。 |

| Abstract: | The fluorescence emission mechanism and some defects existing in conventional fluorescence evaluation methods are discussed. A new method for fluorescence evaluation on mud and mud additives is established on the basis of lots of investigation. The new method can avoid fluorescence quench caused by high concentration of measured fluid and personal error. It is especially suitable for fluorescence analysis of condensate oils, light oils and some mud additives with lower wavelength than 400 nm. Compared with the traditional methods, the new method is more accurate and trustworthy for determining the influencing extent of mud and mud additives on cuttings fluorologging. |
