对塔里木盆地ＹＨ７Ｘ１井寒武系碳酸盐岩储集层岩心样品的热解和岩心抽提物的气相色谱分析表明：油层样品的热解含油率与其储集空间的发育程度密切相关，储集空间发育处含油率可能很高，储集空间不发育处含油率很低（甚至为０），正构烷烃碳数分布范围较宽（１５至３０以上），且正构烷烃丰度相对较高；而水层样品的热解含油率普遍较低，正构烷烃碳数分布范围较窄（１５至２５），且正构烷烃丰度相对较低，碳数高于２５的正构烷烃丰度几乎为０。热解分析与气相色谱技术相结合，有助于预测碳酸盐岩油藏的原油性质和确定其油水界面。图１表１参６（梁大新摘） The gas chromatographic analysis of pyrolysis and core extract of the Cambrian carbonate reservoir in the YH7X1 well in the Tarim Basin shows that the pyrolysis oil content in the oil layer is closely related to the development of its reservoir space. The oil content in reservoirs may be high, the oil content is very low (even 0) in the unconsolidated reservoirs, the carbon number distribution of n-alkanes is wide (above 15-30), and the n-alkanes abundance is relatively , While the pyrolysis oil content of aquifer samples was generally low, the n-alkanes ranged from 15 to 25, and n-alkanes with relatively low n-alkanes and n-alkanes with carbon number above 25 Abundance is almost zero. The combination of pyrolysis analysis and gas chromatography helps to predict the nature of the crude oil in carbonate reservoirs and determine the oil-water interface.
