摘要: 本文利用准噶尔盆地东部北三台地区凝析油及二叠系和侏罗系原油的分析化验结果,简述了凝析油的组成特征,并进行了凝析油/原油对比、热成熟度及生物降解作用的研究。分析了凝析油的油源及生成的时间和条件。研究表明,该区的凝析油来自二叠系生油层,为与湿气相伴生的产物。其中的有些部分遭受了生物降解作用。

Abstract: This paper briefly describes component characteristics of condensates by using analytical and experimental results from the northern Santai and crude oils from the permian and Jurassic in the same area. The ol/oil correlation, thermal maturation and biodegradation of the condensates were studied. lt is shown that the condensates of this area comefrom the permian source locks are products accompanied with wet gas, some of which are subject to biodegradation.

Key words: condensate, light hydrocarbon, oil/oil correlation, thermal maturation, biodegradation
