上篇文章介绍了油气汇聚体系的概念和类型,油气汇聚体系的类型和级别在很大程度上与层序格架的特征、级别有很大关系,本文的目的旨在讨论层序格架中油气成藏单元与层序级次之间的关系,在此基础上,通过建立不同级别的层序地层格架,结合储层的分布和构造断裂等因素,预测油气的汇聚特征。
In last article, the concept of petroleum collective system and its scales are discussed. The type and scales of petroleum collective system are related with the structure of the sequence, different scale are determined by the sequence of different scales. Petroleum collective system of different scale are determined by the sequence of different scales. The ways and the results of exploration in different scaled petroleum collective system of different scale are also different. So, according to the scales of the sequence and systems, the scales and types of oil and gas field or oil and gas reservoir can be predicted and explorated.
