摘要

摘要: 通过对吉林桦甸盆地新生代古近系油页岩热压模拟实验产物的气相色谱-质谱(GC-MS)分析,发现苯并藿烷类化合物在340℃的模拟产物中已经基本消失,而在此模拟温度之前,苯并藿烷指数(BHI)与实测等效镜质体反射率(R_o)具有良好的相关性。因此在烃源岩成熟之前,苯并藿烷指数可以作为一项较好的成熟度评价指标,同时苯并藿烷也可作为未成熟和低成熟烃源岩的特征标志物。

Abstract: Gas chromatography-mass spectrometry (GC-MS) analysis of the thermal simulation products of the Eocene oil shales from the Huadian Basin in Jilin province show that a series of benzohopanoids disappeared at a simulation temperature≥340℃. The benzohopane index (BHI) correlates well to the equivalent vitrinite reflectance, which can be used to judge maturity for low-maturity source rocks, and to distinguish mature and immature source rocks.
