摘　　要：随着定量荧光录井技术研究的深入和应用水平的提高,该技术在储集层流体性质解释评价方面发挥了重要作用,然而在利用该技术评价储集层的产出能力方面尚未进行深入研究。根据产能层样品分析所得油性指数接近标准油样的油性指数而非产能层样品分析所得油性指数与标准油样的油性指数差别较大的特点,定义相对油性指数(Rr)为标准油样油性指数与样品油性指数的差值,其大小反映所测样品与标准油样烃类组分配比关系的相似程度。通过对渤海湾地区42口井该参数与相当油含量的统计分析,结合试油结果,在建立相对油性指数与相当油含量关系图板的基础上,提出了利用这两项参数评价储集层产出能力的标准,进一步的应用分析表明,其应用效果较好,可为勘探开发,尤其是勘探开发方案的实施提供可靠的参考依据。With the deepening study and improving application level of quantitative fluorescence logging technique,the quantitative fluorescence logging technique in interpreting and evaluating reservoir fluid properties plays an important role,while the technology has not yet been deeply studied in reservoir output capacity evaluation.According to the sample analyses of productivity layers that oiliness index is close to the oiliness index of standard oil sample,while sample analysis of non-capacity layers that oiliness index is great different from that of standard oil sample,the relative oiliness index（Rr）was defined as the difference between the oiliness index of standard oil sample and that of the sample oil,the value reflects the similarity degree of the assignment relations between the measured sample and standard oil sample′s hydrocarbon composition.Through the statistical analysis for this parameter and equivalent oil content of 42 wells in Bohai Bay,combining with formation testing results and the establishment of relationship chart between the relative oiliness index and the equivalent oil content,the authors proposed the standards of using these two parameters to evaluate reservoir output capacity.Further analysis showed that the application was better.The method provides a reliable reference for exploration and development,in particular the implementation of exploration and development plans.
