摘要: 油气地球化学参数及指标在含油气系统研究中有着重要的作用。含油气系统的研究主要包括有效生烃灶的确定、关键时刻的确定、油气运移路径的确定、运聚单元边界的确定、资源潜量的确定及目标潜力与级别的确定等6个方面,通过对上述6个方面研究的论述,阐述了油气地球化学手段在含油气系统研究中的具体应用方法。认为:油气地球化学方法贯穿于含油气系统研究的始终,应该重视油气地球化学测试技术及分析手段与含油气系统研究的紧密结合。

Abstract: Petroleum geochemistry parameters and indexes exert great effect on the study of petroleum system. The study mainly consists of six decisions on hydrocarbon kitchen, critical moment, migration pathway, boundary of hydrocarbon migration-and-accumulation units (HAMU), resources potential, target potential and level. Based on the discussion of the six aspects mentioned above, this paper presents the practical application of petroleum geochemistry in petroleum system study. It is considered that petroleum geochemistry can be applied from the beginning to the end of the study. Emphasis needs to be laid on the close combination between geochemistry experiment and petroleum system study.

Key words: petroleum geochemistry, petroleum system, hydrocarbon source rock, critical moment, effect
