Abstract

Both Dongfang and Ledong areas are the main exploration field in Yinggehai Basin.When the organic matter is buried in the same depth,the thermal maturation level of organic matter is higher in Dongfang area than that in Ledong area.The high temperature and overpressure systems have affected the thermal maturation.But,the main reason of the difference of thermal maturation between Dongfang area and Ledong area is the different deposition rates which is caused by the migration process of depocenter during Neogene-Quaternary.The depocenter migration marked a differentiation hydrocarbon generation between Dongfang area and Ledong area.In Dongfang area,the generation begins early and lasts a long time.But,in Ledong area,it initiates late but is fast.The organic acid is also formed late in Ledong area,which contributed to the formation of secondary pore in mid-depth formations.Therefore,there is good accumulation condition and favorable exploration prospect in Ledong area.
