几年来,为了找出大地构造类型和区域含油区之间的经验规律,发展了沉积盆地的大地构造分类。这种途径仅在局部获得了成功,因为,正如Bally所指出的,每种地质分类的盆地,都可以看到任一级别的含油区,从近不毛之地到高产油区。本文所提出的分类是以控制石油生成、运移和圈闭全过程的化学和物理定律为基础的,而不是依据描述性的地质途径。“石油盆地”或石油系统是指在地质空间和时间尺度上起作用的、石油生成和聚集的动力学、物理化学系统。
In recent years, the geotectonic classification of sedimentary basins has been developed in order to find out the empirical laws between the types of tectonic structures and the oil-bearing regions. This approach has only been partially successful because, as Bally points out, basins in every geologic class can see either level of oil-bearing zones, from near-barren land to high-producing oil zones. The classification presented in this paper is based on the chemical and physical laws that govern the whole process of oil production, migration and trapping, not on the descriptive geological route. “Oil basin” or petroleum system refers to the kinetic and physicochemical systems that generate and accumulate oil that play a role in geological space and time scales.
