Abstract:

Rift systems in the world are widely developed in various stages and various environments of plate tectonic cycle,including(1) continental rift,(2) nascent ocean,(3) extensional continental margin,(4) back-arc rift,and(5) collision rift.The forming mechanisms of typical rift systems in the world mainly include(1) active rift,(2) passive rift,and(3) complex rift.Play is the basic assessment unit(AU) of the total petroleum system(TPS). Various kinds of plays are extensively developed in rift basins.According to horizons cut by normal faults and sedimentary system in different tectonic environments,four kinds of plays can be recognized,including(1) tilted fault block belt,(2) rollover structural belt and delta system,(3) slope break belt and reef-bank sequences,and(4) accommodation zone and turbidity fan system.

Key words: play, total petroleum system, rift basin, extensional structures
