摘要
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。
Abstract Oil forming system is a specific phase of petroleum geology,which emphasizes the analysis of the genetic relation between effective hydrocarbon sag and hydrocarbon accumulotion.The rapid development of sequence stratigraphy has led to the applicatim of sequence stratigraphy to various stages of hydrocarbon exploration.The lithologic and lithofacies study derived from sequence stratigraphy has become one of the most important parts in studying the property of oil generation,reservoing and sealing covering.The framework of sequence stratigraphy provides significant information of strata correlation and sedimentary development for trap forming and hydrocarbon migration and accumulation.In the study of newly developed high resolution petroleum system,high resolution sequence stratigraphy can provide a serious of important basic parameters such as bed correlation,reservoir physical analysis,the dynamic analysis of oil,gas and water.Sequence stratigraphy play an important role in petroleum system.
