摘　　要：利用QHD32-6油田稠油油藏原油芳烃组分中的三甲基萘、四甲基萘和五甲基萘系列化合物的分布特征,建立了明化镇组各油层的特征指纹。QHD32-6-3井NmⅡ和NmⅣ油组两端元原油二元配比实验结果表明,利用多甲基萘指纹参数计算2层合采单层产能贡献是可行的。尝试利用多甲基萘参数计算了与QHD32-6-3井和QHD32-6-4井相邻的一些多层合采井的单层产能贡献;将计算结果与生产测井结果进行对比表明,利用多甲基萘参数计算多层合采井单层产能贡献也是可行的。The specific fingerprint of each pay zone is established in Minghuazheng formation according to the distribution features of tri-methylnaphthalenes, tetramethylnaphthalenes and penta-methylnaphthalenes in aromatic fraction of crude from QHD32-6 heavy oil reservoir. A binary combination experiment of two end members for NmⅡ and NmⅣ zones in well QHD32-6-3 has indicated that it is feasible to calculate productivity contribution of each zone in a two-zone commingled producing well by the multi-methylnaphthalene fingerprints. The contribution Of each zone are calculated tentatively by the multi-methylnaphthalene parameters for some multi-zone commigled producing wells adjacent to QHD36-6-3 and QHD32-6-4. The comparison between the results and the PLT data available also shows that the multi-methylnaphthalene parameters are useful to calculate single-zone productivity contribution in a multi-zone commingled producing well.
