摘　　要：在进入勘探开发中后期的油田,应用小井眼侧钻井技术,不但可以节省油气开发成本,而且可以有效提高采收率,恢复老区块的产能。针对小井眼侧钻的复杂井况条件,提出了应用定量荧光录井的差谱技术有效识别真假油气显示,利用其分析参数及解释图板对储集层进行解释评价的方法。在介绍定量荧光录井技术原理的基础上,总结出常用钻井液添加剂的荧光特性及影响程度,并通过对样品的图谱形态分析和参数特征研究,建立了原油性质判别标准、储集层解释评价标准及解释图板。应用结果表明,其油气层解释符合率达到88.6%,油气发现率100%,为老油田增产提供了技术保障。For the oilfields, which are entering into the mid-later period of exploration & development, applying slim hole lateral drilling technique, not only saves oil-gas development cost but efficiently increases recovery factor and recovers deliverability of the maturing blocks. In view of the complex well conditions, the paper put forward using the differential spectrometry technique of the quantitative fluorescence logging to efficiently identify true or false oil-gas shows, and the method in which its analysis parameters and interpretation charts were used to make interpretation and evaluation of reservoirs. On the basis of introducing quantitative fluorescence logging technique principles, the paper summed up fluorescent characteristics and influence extent of common drilling fluid additives, and through analyzing sample spectrum pattern and studying the parameter characteristics, set up oil property discriminating criteria and reservoir interpretation & evaluation criteria and interpretation charts. The applied results indicated that oil-gas layer interpretation coincidence rate reached 88.6 percent, oil-gas finding rate was 100 percent, therefore providing technical guarantee for maturing fields.
