辽河油田的原油来源单一,成熟度相近,本文对取自辽河油田冷东地区遭受不同生物降解作用的14个油样的烷基菲系列进行了详细的分析,对比了不同程度生物降解原油中菲、甲基菲系列和二甲基菲系列浓度的变化,并根据菲及烷基菲异构体在生物降解过程中相对含量的变化,确定了菲及烷基菲系列的生物降解顺序是菲>甲基菲系列>二甲基菲系列,探讨了与烷基菲有关的成熟度参数如F1[F1=(3-MP+2-MP)/(1-MP+2-MP+3-MP+9-MP)]和F2[F2=2-MP/(1-MP+2-MP+3-MP+9-MP)]与生物降解程度之间出现明显的负相关关系,表明这些参数已不能为生物降解原油提供有效的成熟度信息。
In Liaohe Oilfield, the source of crude oil is single and the maturity is similar. In this paper, the alkylphenanthrene series of 14 oil samples from different regions of Liaohe oilfield subjected to different biodegradation were analyzed in detail. , Methylphenanthrene series and dimethylphenanthrene series, and according to the relative content of phenanthrene and alkylphenanthrene isomers during biodegradation, the order of biodegradation of phenanthrene and alkylphenanthrene series was determined as phenanthrene> Methylphenanthrene series> dimethylphenanthrene series, the maturity parameters related to alkylphenanthrene such as F1 [F1 = (3-MP + 2-MP) / (1-MP + 2-MP + 3-MP + 9-MP)] and F2 [F2 = 2-MP / (1-MP + 2-MP + 3-MP + 9-MP)] and the extent of biodegradation showed that these parameters could not Provides effective maturity information for biodegradable crude oil.
