油藏地球化学是近些年在油气地质领域新兴的一门边缘学科 ,利用色谱指纹技术研究混采油层的单层产能贡献是其重要的研究领域之一 .本文以新站油田为例 ,对 9个葡萄花和 3个黑帝庙油组的单层油进行了实验室配比 ,详细探讨了从基础指纹数据库的建立到特征指纹参数的选取 ,并结合数学统计法把 9个葡萄花油组原油分为 4种不同族群 ,而 3个黑帝庙油组原油归为同一族群 ,进而确定了 4种配比方案 ,建立了 4套实验室产能预测图版 ,各个图版分别有相关性较好的关系线 3～ 4条 .经实验室任意自配混合样检验后 ,各图版均优选出相对误差小于 5%的最佳工作线 ,证实了本方法的可靠性与实用性 .
Reservoir geochemistry is an emerging discipline in the field of oil and gas geology in recent years and it is one of the most important research fields to study the contribution of single-layer capacity of mixed oil reservoir by using chromatographic fingerprinting.In this paper, taking Xinchang Oilfield as an example, 9 grape flowers and 3 black oil reservoirs of the single-layer oil laboratory ratio, discussed in detail from the establishment of the basic fingerprint database to the selection of characteristic fingerprint parameters, combined with mathematical statistics to 9 grape flower oil Group of crude oil is divided into four different ethnic groups, and three black Dijiatan oil group into the same group of crude oil, and then determine the four kinds of ratio programs, set up four sets of laboratory capacity forecast plate, each plate were better correlation Of the relationship lines 3 to 4. After the laboratory with any self-mix test, the plates are preferred to the relative error of less than 5% of the best working line, confirmed the reliability and practicality of the method.
