Deepwater zones in global passive continental margin have good conditions of petroleum geology, and huge petroleum resources. At present, about more than 60 countries have explored oil and gas in the deep water and proved recoverable petroleum reserves of about 300×108 t. The four biggest global passive continental margin deepwater zones as rich petroleum accumulation are becoming hot exploration area, such as Brazil offshore, America Mexico gulf, west Africa offshore, and Asia-Pacific area, and are the important domains of recent discovery of large oil-gas fields. 33 giant oil and gas fields were discovered in the passive continental margin deepwater zones in years of 2000-2007, accounting for 42% of the global total discoveries. Based on discovery of oil and gas fields in deepwater zones and their features of petroleum system, petroleum geology was discussed in combination with Chinese passive continental margin deepwater zones. Then we discuss their discoveries for the implication of petroleum exploration in South China Sea and next exploration plan. In feature years, petroleum exploration in deepwater of South China Sea should be paid attention as national strategy, and research of exploration target evaluation and optimal selection in deepwater zones be strengthened.
