摘要

摘要: 通过对塔河地区22个原油样品的饱和烃色质、芳烃色质和饱和烃色谱的定量分析研究表明，塔河地区中南部和东部原油的二苯并噻吩和姥鲛烷含量高于中北部地区的原油，说明前者代表碳酸盐沉积环境，而后者的缺氧程度更大；中北部地区原油的C₃₅升藿烷含量高于东南部地区的原油，说明水体分层更明显，其还原程度更强；C₂₉S构型甾烷含量越低，二苯并噻吩含量和2-甲基菲+3-甲基菲含量越高，原油的成熟度越高；中北部地区原油的25-降藿烷和二降藿烷含量高，为生物降解原油。

Abstract: 22 crude oils of the Tahe Oil Field have been quantitatively analyzed with gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) for saturate and aromatic biomarkers. The contents of dibenzothiophene (DBT) and pristane (Pr) of middle-south and east area oils are relatively higher than those of middle-north area, which indicates that the former has a depositional environment of carbonite and stronger reducing environment than the latter. The content of C₃₅ homohopanes is higher in the oils of middle-north area than those of south-east, indicating for delamination water body of the former and stronger reducing environment. The content of C₂₉S steranes increases with that of DBT and methyl phenanthrenes and maturity degree. The high contents of 25-norhophane and bisnorhopane in middle-north area reveal the experience of biodegradation.
