利用HP6890型高温气相色谱（HTGC）剖析辽河盆地大民屯凹陷高蜡原油。研究结果表明：高蜡原油中显著存在碳数高达C40－C60以上的高碳数烷烃类，主要为正构烷烃；常规气相色谱受到柱系统热稳定性的限制，仅能提供碳数小于C35的化合物信息，而高温气相色谱可以分析C35以上的烧烃。这类高碳数正构烷烃的识别为重新描述高蜡原油的物理化学性质，探讨其有机质来源及成因，评价储层中残留的重质组分提供了理论依据。
Analysis of High Wax Crude Oil in Damintun Depression of Liaohe Basin by HP6890 High Temperature Gas Chromatography (HTGC). The results show that there are significant high-carbon alkanes with carbon number up to C40-C60 in high-wax crude oil, mainly n-alkanes. Conventional gas chromatography is limited by the thermal stability of the column system and can only provide carbons less than C35 Compound information, while high temperature gas chromatography can be analyzed above C35 burning of hydrocarbons. The identification of such high-carbon n-alkanes provides a theoretical basis for re-describing the physicochemical properties of high-wax crude oil, exploring its source and origin of organic matter, and evaluating the residual heavy components in reservoirs.
