摘要
金刚烷系列化合物具有较高的稳定性,可作为衡量原油成熟度和识别原油裂解程度的指标.采用内标法,利用气相色谱-质谱(GC-MS)仪在平湖斜坡带的原油样品中检测到金刚烷系列化合物,并对其进行了绝对定量分析;根据3-和4-甲基双金刚烷绝对含量和生物标志化合物的绝对含量,参照金刚烷成熟度参数的关系确定了该区原油成熟度在0.98%~1.45%之间,推算了原油的裂解程度大致位于70%~80%之间.
Series of diamantane hydrocarbons had high stability,a large number of them existed in crude oil,they could be the indicator for setting the maturity of crude oil and identifying the degree of oil cracking.By using internal standard method and GC-MS in several crude oil samples from Pinghu Slope Belt,the series of diamantine hydrocarbons were detected and absolute quantitative analysis was carried out for them.According to the 3-/4-methyl double diamondoild and absolute content and the absolute content of biomarker compound and referring to diamantane maturity parameters,it is determined that the maturity of crude oil in the area between 0.98%~1.45%,and it is estimated that the degree of cracking of crude oil is roughly between 70%~80%.
