含油气系统概念在1972年由美国石油地质学家Dow首先提出,历经Perrodon,Demaison,Meissner,Ulmishek及Magoon等人补充、修改而完善。含油气系统为一个有效源岩体和所有有关油气的天然系统,包括油气藏存在所必需的一切地质要素和作用,与沉积盆地、成藏组合和勘探目标等层次构成一个油气调查序列,侧重研究生油气源岩体与油气之间的成因关系。因此,含油气系统不属新理论范畴,而是一种适用于研究油气的新方法,研究对象为某一油气成因单元。含油气系统因地质要素和地质作用的不同功能,可进一步划分为生成子系统、运移子系统和聚集(保存)子系统。我国的含油气系统不仅仅由单一系统构成,而多发育复式含油气系统。在引进和应用含油气系统的方法时,不要盲目套用,也不要不切实际地进行所谓的修改与创新,而应视我国的具体地质情况而定。

The original concept of petroleum system was put forward by an American petroleum geologist Dow in 1972,and then it was supplemented and improved by Porrodon,Demaison,Meissner and others.The petroleum system consists of a effective source rock mass associated with all relative natural hydrocarbon systems and necessary geological elements for oil and gas pools.The petroleum system,together with sedimentary basin,pool-forming assemblage and play,constitute a petroleum investigation series.So the petroleum system does not belong to the category of new theory,but really a new method suitable for oil and gas researches.The object of the research is a petroleum unit of certain origin.The petroleum system could be divided into generation subsystem,migration subsystem and accumulation(preservation)subsystem due to different geological elements and functions.The petroleum systems in China are usually complex systems.When introduce and apply the method of this system,one should neither apply it indiscriminately,nor revise it without considering our own geological condition.
