摘要
原油全烃气相色谱指纹的变化是原油非均质性的具体表现,也是将该技术应用于油藏开发的基本依据。将原油气相色谱指纹技术应用于鄂尔多斯盆地某区长62油层连通性研究,优选出的产层连通性原油色谱指纹特征对比结果显示,研究区长62层原油可分为五种类型:Ⅰ类、Ⅱ类、Ⅲ类、Ⅳ类和特殊油,除特殊油外,同类原油分布与产层砂带分布特征基本一致,并显示出较好的连通性,不同砂体之间油藏的连通性和保存条件存在着差异,测井、试油资料也进一步验证了指纹分析结果的可靠性。
The basic principle of using gas chromatographic finger print technique in reser-voir development was that the changes of full hydrocarbon gas chromatographic fingerprint were representations of heterogeneity of oil. The gas chromatography fingerprint technique was applied to understanding of oil layers connectivity of chang 6 oil of a certain area in Ordos Basin. According to the chromatographic fingerprint parameters, the oil of studied area can be divided into five types： Ⅰ-Ⅳ types and the special type. Except for the special type oil, the oil of same type was basically in agreement with reservoir sand distribution charac-teristics and was in good connectivity. There was difference in oil layer connectivity and preservation condition among different sandbodies. The results of the well logging, testing for oil, and layering data shows that crude oil chromatographic fingerprint technology was a re-liable method in researching connectivity of layers.
