Zusammenfassung:The invention discloses a fractured-vuggy oil reservoir single well nitrogen injection effect comprehensive evaluation method and device. The method comprises: aimed at each fractured-vuggy oil reservoir single well, obtaining an evaluation index set according to a pre-established evaluation index set; obtaining evaluation index data of the single well; according to the evaluation index data of the single well, determining the weight of each evaluation index used for evaluating the nitrogen injection effect of the single well, according to the weight of each evaluation index used for evaluating the nitrogen injection effect of the single well, determining the evaluation score of the single well, and performing effect evaluation on the single well according to the evaluation score of the single well and a preset score effect table. Through the method, the evaluation index is combined with the evaluation index data of the fractured-vuggy oil reservoir single well, the nitrogen injectioneffect of the fractured-v
