摘要:

临南洼陷沙四上亚段泥岩中有机质类型以Ⅱb型为主,有机碳含量为0.05%以上的样品约占样品总量的68%,而有机质含量较高的泥质岩中S1+S2值基本上都大于0.5 mg/g以上。所采集样品的有机质演化程度不是很高,但有相当一部分已基本达到或近于达到了生油的成熟状态。在所采集的两个源岩对比样品中,C15+正构烷烃、类异戊二烯烃和生物标志化合物指纹图等都显示了较好的相似性,说明临南洼陷沙四段泥岩具有一定的生油能力,并且已经确实出现了原油的排烃过程。

Abstract:

Ⅱb is the dominant type of organic in mudstone in Es4 of Linnan sag, organic carbon of about 68% samples are more than 0.05%, and value of S1+S2 are more than 0.5 mg/g in mudstone with higher organic content. The organic doesn't reach a much higher degree of organic evolvement, however, organic in some samples do reach the state of hydrocarbon generating. In order to make clear if mudstone in the study area had ever generated hydrocarbon, two samples of mudstone and oil-containing sandstone were chosen from a near depth, the biomarkers in the samples all show better comparability, which means that the mudstone in Linnan sag has some hydrocarbon generating potential, and do have generated hydrocarbon.

Key words: Es4 Member, hydrocarbon source rock, hydrocarbon generating potential, Linnan sag
