从油藏地球化学角度出发,以临邑洼陷夏502块沙三下段、商546块东二段和大芦家区块馆二段为例,运用含氮化合物分布特征与传统全油色谱指纹技术进行油藏储层和流体连通性的对比研究。研究表明:同一井区范围内如果原油含氮化合物参数分布特征相似,则油藏和流体连通性好,反之则连通性较差;含氮化合物较色谱指纹抗生物降解能力强,更适合于对遭受生物降解的油藏连通性进行预测;在预测储层连通性时,含氮化合物的精细识别和可鉴定特征可用于不同学者之间重复性和对比性的研究。
From the point of view of reservoir geochemistry, taking the second section of Sha 3, Xia 502 in Shangyi depression, Shang 2 section of Shang 546 block and the second section of Block in Dalujia section as an example, the distribution features of nitrogenous compounds were compared with those of the traditional whole oil chromatography fingerprinting A comparative study of reservoir and fluid connectivity was conducted. The results show that: if the distribution characteristics of nitrogen compounds in crude oil are similar in the same well area, the connectivity between reservoir and fluid is good, otherwise the connectivity is poor; nitrogen compounds are more suitable for the biodegradation than the chromatographic fingerprints Predicting reservoir connectivity that is biodegradable; the finely identified and identifiable features of nitrogen-containing compounds can be used for reproducibility and comparability studies among different scholars in predicting reservoir connectivity.
