摘要:

层序地层格架和成藏动力系统都以地层沉积的多期旋回性作为层序或子系统划分的依据。文章讨论了层序地层格架与成藏动力系统在划分上的耦合,指出最大洪泛面既是层序地层格架中的重要界面又是成藏动力系统子系统划分的界面;探讨了层序地层中的体系域与成藏动力子系统在成藏条件包括烃源灶、侧向疏导体系、封盖层、隐蔽圈闭等方面的关系,指出了生、运、聚等成藏作用研究在应用层序地层学寻找隐蔽油气藏中的重要作用,强调遵循"油气从源岩到圈闭"的思路是应用层序地层学技术寻找隐蔽油气藏的灵魂。

Abstract:

Both sequence stratigraphic frameworks and hydrocarbon reservoiring dynamic systems employ the multi-cyclicity of stratigraphy sedimentation as the basis of sequence or subsystem division.This article discusses the coupling of sequence stratigraphic frameworks and hydrocarbon reservoiring dynamic systems and points out that the maximum flooding surface not only serves as the important boundary in sequence stratigraphic frameworks,but also acts as the boundary for dividing subsystems in the hydrocarbon reservoiring dynamic systems.It analyzes the relationship between the sequence stratigraphy system tracts and hydrocarbon reservoiring dynamic subsystems in terms of hydrocarbon accumulation conditions,which include source kitchens,lateral carrier systems,sealings and subtle traps.It also stresses the importance of research on oil and gas pooling processes,such as hydrocarbon generation,migration and accumulation in subtle reservoir exploration by using sequence stratigraphy theories.Moreover,it emphasizes that abiding by the concept of "hydrocarbon from source rocks to traps" is essential to the application of sequence stratigraphy technologies in the exploration of subtle reservoirs.

Key words: coupling, interface division, subsystem, system tract, hydrocarbon accumulation dynamics, sequence stratigraphy
