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。
Total hydrocarbon geochemical method not only can effectively solve the problem of complex hydrocarbon source and hydrocarbon source, but also provides evidences of hydrocarbon migration and accumulation, storage conditions and redistribution in various phases, clarifies the history and process of hydrocarbon accumulation, and effectively guides oil and gas exploration. Light hydrocarbons are an important part of petroleum and natural gas. With the deepening of research on light hydrocarbons by domestic and foreign scholars, the role of light hydrocarbon in geochemical analysis of all hydrocarbons has become more and more significant. Based on the previous studies, the research results on the application of light hydrocarbon parameters are reviewed. The light hydrocarbon parameters are summarized to determine the type and environment of hydrocarbon generating parent materials, to infer the extent of thermal evolution of organic matter, to compare hydrocarbon sources, to study the hydrocarbon migration Direction and phase type, to determine the application of oil and gas preservation conditions.
