摘　　要：吉林探区储集层原油性质复杂,低显示油层和高显示水层普遍存在,单纯靠常规地质录井难以准确进行油水层解释评价。针对该情况,通过大量基础数据的统计分析,结合试油结果对比,应用定量荧光录井技术谱图形态识别法、油性指数划分法,实现了储集层原油性质的有效识别,在此基础上建立了油性指数与相当油含量解释评价图板。实例验证表明,利用该图板可准确评价不同原油性质储集层,对低显示油层、高显示水层和一般显示油水同层有较好的应用效果,解释符合率由原来的75.0%左右提高到89.6%。Crude oil property is complex in the reservoir in Jilin exploration area,and the low show oil layers and high show water layers are commonly existed,therefore it is difficult to accurately interpret and evaluate oil-water layers by simply relying on the conventional geologic logging.According to such a situation,through statistical analysis on a large number of basic data and combining with the results of oil testing comparison,the effective identification for the reservoir crude oil nature was realized by applying the method of the spectrum shape recognition and oil nature index classification of the quantitative fluorescence logging technology.Based on this,the interpretation and evaluation chart for oil nature index and the equivalence oil content was set up.The examples showed that using the chart could accurately evaluate the reservoirs of the different crude oil nature,and it had good effects especially to the oil layers with low show,water layers with high show and oil-water layers with common show.The interpretation coincidence rate was increased from the original 75% to 89.5%.
