AN APPLICATION OF INFRARED SPECTROMETRY IN CLASSIFYING THE ORGANIC MATTER TYPES OF SOURCE ROCKS
-
摘要: 生油岩有机质类型或性质对其生油潜力有重大的影响。笔者选用了松辽盆地白垩系青山口组一段和鄂尔多斯盆地北部上古生界中石炭系羊虎沟组、上石炭系太原组及下二叠系山西组等生油岩共计60个样品,应用红外光谱法探讨有机质类型,并提出烷芳基团结构比(∑Rcm1/∑Arcm1)作为有机质类型的判别指标。Abstract: In this paper, infrared spectrometry is used in probing the organic matter type of source rocks from the 1st member of Qingshankou Formation, Cre-taceous in Songliao Basin and Yanghugou Formation, Middle Carboniferous in Upper Paleozoic, Taiyuan Formation of Upper Carboniferous and Shanxi Formation, Lower Permian in Ordos Basin. Meanwhile, it presents the structure ratio of alkyl/aryl (ER cm1/EAr cm1 which can be taken as an indicator for identifying organic matter type.
