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
