摘要

运用反映原油整体面貌及反映原油组成的成熟度参数对莺-琼盆地原油(凝析油)进行综合研究后认为,莺-琼盆地原油(凝析油)主体可能是成油高峰期的产物,但有程度不同的未熟―低熟原油的混入。凝析油并不一定是高温裂解的产物,在相应地质条件下,正常的成熟度也可形成凝析油。金刚烷业已用于原油成熟度研究,但在莺―琼盆地未熟―低熟油样品抽提物中均发现了单、双金刚烷,说明金钢烷不一定只受高温条件的控制,其形成还可能受沉积环境的影响,故将金刚烷参数用作成熟度指标时要慎重。

Abstract

Using the multi-parameters that reflect the characters of crude oil studied the maturity of crude oil in Yingqiong basin and it was considered that the crude oil was generated mainly after the most active oil-generation time, but intermingled by immature oil or so called \"pollution\". Condensate can generate in normal maturity and was not always generated under high temperature or cracking.The parameters of diamonoid hydrocarbons can be used as maturity, but the evidence that diamonoid hydrocarbons.

Key words： Yingqiong basin; Maturity; Condensate; Mango parameter; Diamonoid hydrocarbon.
