摘要
为了探讨新站油田流体非均质性分布规律及成因 ,利用新站油田 2 2 8个油砂抽提物的族组成特征、饱和烃气相色谱、生物标志物组成特征等多种资料 ,选用不同参数 ,利用传统的关系图件法 ,并首次尝试运用数学统计方法 ,来划分原油族群 .在总结族群划分结果的基础上 ,分析了不同族群的分布规律 ,初步探讨了其形成控制因素 .结果表明 ,葡萄花油组油砂可区分为三种类型 ,而黑帝庙组油砂有两种不同类型 .在此基础上 ,对不同族群分布规律的对比分析发现造成两油组几种族群的主要原因是受到构造和岩性因素的控制 ,此外次生改造作用也是影响族群分布的因素 .
The division of petroleum populations is the basis of studying fluid heterogeneity, reservoir connectivity, reservoir filling history, and so on, so it plays an important role in the research of reservoir geology, especially of reservoir geochemistry. The petroleum populations of Xinzhan Oilfield were divided according to the group composition, saturated hydrocarbon gas chromatogram, biomarker composition of 228 oilsand extracts by means of traditional graphic method and mathematical statistics method. The distribution patterns of different populations and their control factors were analysed based on the result of the division. The analysis results show that, the oilsand of Putaohua oil-bearing formation is divided into three types, and that of Heidimiao oil-bearing formation is divided into two types. It is held that the structural and lithologic factors lead to the different populations of the two oil-bearing formations.
