Abstract: Basin is the essential unit for hydrocarbon generation and migration.But among the hydrocarbon accumulation conditions,the abundance of hydrocarbon and the reservoir characters,there are many differences longitudinally and horizontally within a basin,so the sub unit of explorating evaluation needs be divided.After analyzing all kinds of basins in the world,it is found that in the hydrocarbon accumulation and the explorating-engineering conditions in the same basin there are many bigger differences in different longitudinal formations than in different structural belts.Accumulation association which is based on the longitudinal formations,they can fit all kinds of basins well when used as the basic exploration unit,and is particularly valueable for the long-time developped multicycle basins.

Key words: petroleum explorating evaluation system, accumulation association, Sumatra, trap evaluation, Ordos, Bohai Gulf, Pre-Caspian Basin
