Abstract

This study presents a systematic geochemical analysis of Paleogene crude oils and source rocks from the Raoyang Sag in the Jizhong sub‐basin of the Bohai Bay Basin (NE China). The geochemical characteristics of fifty‐three oil samples from wells in four sub‐sags were analysed using gas chromatography (GC) and gas chromatography – mass spectrometry (GC‐MS). Twenty core samples of mudstones from Members 1 and 3 of the Eocene‐Oligocene Shahejie Formation were investigated for total organic carbon (TOC) content and by Rock‐Eval pyrolysis and GC‐MS to study their geochemistry and hydrocarbon generation potential. The oils were tentatively correlated to the source rocks.

渤海湾盆地饶阳凹陷古近系原油及烃源岩生物标志物地球化学油源岩对比研究

本文对渤海湾盆地冀中盆地饶阳凹陷古近系原油和烃源岩进行了系统的地球化学分析。采用气相色谱(GC)和气相色谱-质谱(GC - MS)分析了4个亚凹陷井中53个油样的地球化学特征。摘要对始新统—渐新统沙河街组一段和三段20份泥岩岩心样品进行了总有机碳(TOC)含量测定，并通过岩石热解和气相色谱-质谱分析研究了泥岩的地球化学特征和生烃潜力。初步将油与烃源岩进行了对比。
