Hydrocarbon migration and accumulation dynamics studies various driving forces of hydrocarbon migration and accumulation

geodynamic background of basins

and dynamic systems for hydrocarbon migration from source rocks to traps and entrapment.The dynamic system not only serves as a carrier for hydrocarbon migration and accumulation dynamics

but also occupies a very important place in the dynamics studies.It consists mainly of hydrocarbon expulsion units and their combinations

subsystem of hydrocarbon migration and accumulation dynamics

pathway systems.The progresses in the study of dynamic systems include(1) the application of sequence stratigraphy to the determination and classification of the dynamic systems

resulting in a better understanding of the fact that the maximum flooding surface is critical for recognizing and classifying the dynamic systems;(2) achievements on the study of the dynamic system in the areas with abnormal pressure compartments;(3) researches on the role the tectonic dynamics in the process of hydrocarbon generation
