本文以气侯带为基础，提出含油气超系统的概念及分区。一个含油气超系统可以由若干个盆地组成，超出含油气区的范围，但具有更强的时间限制性。在此基础上再根据盆地构造风格划分出三大类含油气系统：伸展裂陷型、坳陷型和挤压型。一个盆地可以由一个或多个不同类型含油气系统迭合而成。不同类型含油气系统具有不同的构造风格、储集层风格、圈闭风格、油气分布风格。断层系统、不整合系统和地层相变使得油气在横向和纵向上的分布趋于复杂化。含油气系统的研究对老区新带和新区新盆地的勘探具有重要作用。
Based on the climatic belt, this paper proposes the concept and zoning of petroleum-rich systems. A hydrocarbon-rich system can consist of several basins that go beyond the hydrocarbon-bearing area but have greater temporal constraints. Based on this, three types of petroleum systems are divided according to basin structural styles: extensional rifting, depression and extrusion. A basin may consist of one or more different types of petroleum systems. Different types of petroleum systems have different structural styles, reservoir styles, trap styles and oil and gas distribution styles. Fault systems, unconformity systems and stratigraphic changes make the distribution of oil and gas in the horizontal and vertical directions more complicated. The study of petroleum system plays an important role in the exploration of new zone in the old area and new basin in the new area.
