摘要
基于生物标志物的色谱-质谱分析、组分碳同位素、单体烃碳同位素的分析技术,研究了严河地区高成熟原油与本区烃源岩的相互关系,确认了严河地区的高成熟原油来源于本地区的泥晶灰岩。通过对储层中包裹体组成的对比分析以及对包裹体的均一温度的研究,认为严河地区潜四段第一期成熟原油的充注大致在Eq2末期到Eq1末期,而第二期高成熟原油的充注时间是在荆河镇组末期至广华寺组。
This paper,using analysis techniques of biomarker chromatography-mass spectrometry,component carbon isotope and individual hydrocarbon isotope,studies the relations between high matured oil and source rock in Yanhe area and confirms that its high matured oil derived from its micrite.Based on the contrastive analysis of inclusion component in the reservoir and the homogenization temperature study of the inclusion,the paper holds that charging time of firstphase matured oil in Qian 4Member was roughly from the last phase of Eq2 to the last phase of Eq1 while that of second-phase high matured oil was from the last phase of Jinghezhen Formation to Guanghuasi Formation period.
