摘要
全烃地球化学方法不仅可有效解决复杂油气成因与烃源问题,而且可提供各期油气运聚、保存条件以及再分配的证据,明确成藏历史和过程,从而有效指导油气勘探。轻烃是石油和天然气中的重要组成部分,随着国内外学者对轻烃研究的日益深入,轻烃技术在全烃地球化学分析中的作用越来越显著。在前人研究的基础上,对有关轻烃参数应用的研究成果进行综述,系统总结了轻烃参数在判断生烃母质类型与环境、推测有机质热演化程度、进行油气来源对比、研究油气运移方向与相态类型、判断油气保存条件等方面的应用。
The geochemical method of total hydrocarbon can deal with complicated genesis and source of hydrocarbon,provide evidences of migration,preservation and redistribution,define hydrocarbon accumulation history and process,and thereby effectively guide hydrocarbon exploration. As the deepening of light hydrocarbon study,light hydrocarbon technique plays an increasingly important role in geochemical analysis of total hydrocarbon. This paper summarizes the results of previous studies,and illustrates the application of light hydrocarbon parameters in diagnosing parent material and environment,assuming the thermal evolution degree of organic matter,performing oil and source rock correlation,probing into hydrocarbon migration direction and phase types,and identifying hydrocarbon preservation conditions.
