| 摘 要： | 热流体活动可以改变盆地的温-压场，对有机质演化和油气生成具有重要的强化作用。珠江口盆地是我国非常重要的海上舍油气盆地。盆地的形成与演化受到了印度板块向欧亚大陆板块俯冲和太平洋板块向欧亚大陆板块俯冲的联合控制。五期重要的构造活动和岩浆作用决定了盆地演化的复杂性，造成了盆地地温梯度和热流值均高，促进了盆地的热流体形成与活动，也使得盆地内烃源岩成熟加速。包裹体等分析表明，盆地油气运移始于晚渐新世-早中新世，延续至第四纪。目前研究表明，油气运移至少经历了两期。

| Abstract: | The activities of hot fluid flow exert a great influence on the tempo-pressure field in a basin and encourage the evolution of organic matter and generation of petroleum. Hot fluid flow , generally, falls into 4 types: mantle fluid, basin fluid, metamorphose fluid and magmatic fluid. The Pearl River Mouth Basin, which is an important oil-bearing basin in the South China Sea, has subjected to the collision of the Indian Plate with the Eurasian Plate and the subduction of the Pacific Plate into the Eurasian. Five important tectonisms and magmatisms cause the sophisticated evolutionary history and high geothermal gradient and heat value for the Pearl River Mouth Basin. Inclusion data shows that the migration of petroleum in the basin initiated from the Late Oligocene to the Early Miocene, up to the Quaternary. Two important migrations at least occurred in the hydrocarbon evolutionary history. |
