摘要

摘要: 通过三元、超临界及氯仿抽提对渤海湾盆地东营凹陷古近系沙河街组四段下部的4个烃源岩样品进行了抽提量、族组分及色谱特征等分析和对比。抽提量对比研究表明:超临界抽提萃取能力较弱;三元抽提则具有相对较强的萃取能力,特别是在成熟度较高的烃源岩评价中,可能是一种相对有效的方法。族组分及色谱特征对比表明:三元抽提对中高碳数正构烷烃及杂原子化合物的萃取能力较强,其色谱特征与氯仿抽提物有较大区别;而超临界抽提对低分子量烃类萃取能力较强,其色谱特征与氯仿抽提物相似。

Abstract: In the paper,the extractive contents,group components and chromatography of four source rock specimens in the lower part of the Fourth Member of Shahejie Formation of Paleogene,the Dongying Sag of the Bohai Bay Basin was analyzed,using the methods of the ternary extraction,supercritical extraction and chloroform extraction.The extractive contents showed that the capability of ternary extraction is higher than that of supercritical extraction,and ternary extraction may be a relative effective method especially in the evaluation of higher maturity source rock.The contrast of group components and chromatography characteristics showed that the capability of extracting middle-high carbon number n-alkanes and heteroatom-containing compounds by ternary extraction is higher than that of supercritical extraction and the chromatography characteristics of ternary extract is different from that of chloroform extraction,but the chromatography characteristics of supercritical extract is similar to that of chloroform extraction.
