成油体系是油气勘探地质研究进程中一个特定阶段的研究目标和任务，侧重于解剖一个有效生油凹陷与其油气聚集间的成因关系；但层序地层学的飞速发展，使它已渗入到石油勘探的各个阶段中。层序地层学导出的岩性、岩相研究已成为生储盖特征研究的主要内容之一，层序地层格架的建立更为圈闭形成和油气运聚过程研究提供了重要的地层对比与沉积演化资料，而在初露端倪的高分辨率成油体系（成藏动力学）研究中，高分辨率层序地层学研究提供从小层对比、物性分析，到油水动态分布研究等一系列重要基础资料，因此，在成油体系分析中，层序地层学扮演着一个举足轻重的角色。以两个陆相盆地的勘探实例，讨论了成油体系分析中层序地层学研究的重要性。
Oil-forming system is the research goal and task of a specific stage in the process of oil and gas exploration geology research, focusing on dissecting the genetic relationship between an effective oil-producing depression and its hydrocarbon accumulation; however, the rapid development of sequence stratigraphy has made it permeate into petroleum In all stages of exploration. The study of lithology and lithofacies derived from sequence stratigraphy has become one of the main contents of the research on the characteristics of the reservoir-reservoir-caprock. The establishment of the sequence stratigraphic framework is more trapping and the study of hydrocarbon migration and accumulation provides important stratigraphic correlation and Sedimentary evolution data, and in the study of high resolution oil accumulation system (accumulation kinetics), the study of high resolution sequence stratigraphy provides a series of important from small layer contrast, physical properties analysis, to oil and water dynamic distribution research As a result, sequence stratigraphy plays a decisive role in the oil system analysis. Taking the exploration of two continental basins as an example, the importance of sequence stratigraphy research in oil system analysis is discussed.
