金刚烷为具有类似金刚石结构的一类刚性聚合环状烃类化合物,是生物标志物等多环烃类在热力作用下经强路易斯酸催化剂聚合反应的产物.目前在地质体中已检测出单金刚烷、双金刚烷、三金刚烷,以及四金刚烷、五金刚烷和六金刚烷.金刚烷化合物是一类具有重要地球化学意义的化合物.我们首先建立了金刚烷成熟度指标,并研究了塔里木和莺-琼等盆地高成熟度原油和凝析油的成熟度.文中介绍我国多个含油气盆地原油、凝析油以及烃源岩中金刚烷化合物的GC-MS分析鉴定结果,并对它们在相对含量上的分布特征进行有意义的研究.
Adamantane is a kind of rigid polymeric cyclic hydrocarbon compound with similar diamond structure and is the product of polycyclic hydrocarbons such as biomarkers which are polymerized by strong Lewis acid catalyst under the action of heat.At present, Adamantane, adamantane, adamantane, tetramantane, pentamantane and hexamantane, adamantane compounds are a group of important geochemical compounds.We first established the adamantane maturity index and studied The maturity of high maturity crude oil and condensate in the Tarim and Ying-Qiong basins, etc. The results of GC-MS analysis of crude oil, condensate oil and adamantane compounds in several hydrocarbon-bearing basins in China are described. Their relative content of the distribution of the characteristics of a meaningful study.
