外文摘要：Southeast Asia (SEA) has broad prospects for cooperation in the Belt and Road Initiative. The potential of hydrocarbon resources in SEA is discussed by analyzing the basin types, resource endowment differences, and controlling factors of hydrocarbon distribution, along with the recent progress of oil and gas exploration. The results show that convergent continental margin, divergent continental margin, and Continental interior basins in SEA are formed by unidirectional drift, convergence and collision of the Tethys tectonic domain, and hydrocarbon reserves account for 34.24 %, 38.94 % and 26.83 %. Basin type, source rock type and maturity, late structuration, and oil and gas type are the main factors controlling hydrocarbon enrichment. In the past ten years, the total recoverable hydrocarbon reserves discovered in SEA were approximately 1.54 x 105 mmboe, accounting for 4.8 % of the total reserves discovered in the same period. The newly discovered reserves are characterized by more gas and less oil, with natural gas accounting for 93.2 %, and the areal extent scale of the individual reservoirs is small. The exploration campaign, characterized by a low commercial success rate (10.9 %) and modest average recoverable reserves (16.01 Mmboe per discovery), demonstrated that the stratigraphic trap play concept did not meet expectations. The recoverable resources of hydrocarbons to be discovered in the main basins of SEA are approximately 3.15 x 104 mmboe and 5.07 x 104 mmboe, respectively. The new field of mature basins is the leading force for exploration and reserve increases. The undiscovered hydrocarbon resources are mainly distributed in these areas, especially in the deep-water areas of mature basins.
