The fan delta, sand beach, sand bars and turbidite fan in the TST of SⅡ and SⅢ sequences are the most favorable exploration targets because of favorable source - reservoir - seal assemblages. Since the high - stand system tract in SⅡ sequence has good source - reservoir assemblage and is covered by the regional seal of SⅢ sequence, the hydrocarbon accumulation in this area is controlled by the local seal rock. The HST of SⅡ sequence becomes the second favorable exploration target zone. Because the scales of the sand bodies of alluvial fan and braided river in low - stand system tract of SⅡ and SⅢ sequences are limited, the formation of a large hydrocarbon accumulation is difficult.
