Abstract: Based on oil and gas prospecting practice, this paper presents the contradictions between studied conventional reservoir-formed stages and field situations,and evaluates the application of technologies as fluid inclusion enclaves analysis, autogenous llite isotopic dating to determination of reservoir-ormed stage, then points out some mistakes existed in precondition assumptions, tchnical principles and practical ranges. Also, positive connections between seismic infornation and petroleum systems are analyzed. The result shows that a principal kinetic factor for reservoir fluid migration is fault-fold structural movement in which episode potential hydrocarbon source rock could provide large-scale hydrocarbons drainage, migration, accumulation and forming reservoirs.
