摘要：

运用钌离子催化氧化(RICO)技术,研究了轮南和塔河油田以及TD2井稠油沥青质。在轮南和塔河油田稠油沥青质分子结构中,键合在沥青质芳核结构中的官能团以烷基侧链为主,烷基桥次之,此外还有一定的支链烷烃及生物标志物,这些化合物绝大部分是以C-C键键合在沥青质结构中的。沥青质中的芳核体系大多以萘、菲、联苯型为主,高度缩合的芳核结构较少。轮南和塔河油田稠油沥青质RICO产物具有较高的一元和二元酸比值,甾烷酸的异构化参数均大于0.40,表明原油具有较高的成熟度;一元酸和甾烷酸的分布均与典型寒武系生源的TD2井稠油具有明显的差异,指示轮南和塔河油田稠油源于中上奥陶统烃源岩。

Abstract:

The asphaltenes of the heavy oils from Lunnan, Tahe oilfie lds and TD2 well were studied by ruthenium-ions-catalyzed oxidation. The subst ituted functions bounded on the aromatic structure of the asphaltene were domina ted by n-alkyl chains, with n-alkyl bridges secondary. A certain amount of bra nched alkanes and biomarkers were also identified. Most of these compounds were  bounded on the asphaltene through C-C bounds. The aromatic systems of the aspha ltenes were dominated by naphthalene, phenantherne and biphenyl, with little hig hly condensed aromatic system. The products of the asphaltene RICO with high n- alkanoic/di-n-alkanoic acid ratios and the isomeric ratio of the steranoic aci d great than 0.4 suggested that the oils have high maturity. The distributions o f n-alkanoic and steranoic acids of the products of asphaltenes RICO of heavy o ils from Lunnan, Tahe oilfields showed great difference from that of the oils fr om TD2 well, a typical oil from the Cambrian, indicating the heavy oils from Lun nan and Tahe oilfields were originated from middle-upper Ordovician. 

Key words: Asphaltene, Heavy oil, Ruthenium-ions-catalyzed oxidation（RICO）, Biomarker, Tarim basin.
