摘　　要：分析世界一些地区油气勘探开发过程中实际探明的地质储量超过计算的油气资源量、累计产油量超过可采储量、在开发过程中油气有新组分增加等现象,认为一些油气田有新生油气源补给,石油和天然气是可以再生的。根据加利福尼亚Guaymas盆地南海槽热液石油的14C同位素年龄以及1δ3C值,认为该类热液石油是近代生成的,其可能的生成模式是高温热液流体对沉积有机质的作用加速了石油的生成,深部地幔流体上升到中地壳,通过费-托反应合成石油。煤矿瓦斯爆炸事件、森林大火事件以及温室气体CO2的排放可能无不与深部地壳无机气体物质源及不断供给有关。石油、天然气的再生表明它们可以通过无机反应生成。The exploration and development of oil-gas fields in the world during the past several decades show that the aetually proved reserves are higher than the calculated resources, the accumulative oil products are higher than the recoverable reserves, and there are some regenerative oil and gas in the fields. Oil and gas are regenerative. ^14C dating and carbon isotopic tracing of hydrothermal petroleum in the Guaymas Basin show that the hydrothermal petroleum is generated in recent epochs. The possible generation models of hydrothermal petroleum are that hot fluids accelerate the petroleum generation by organic matter （such as plus H2）, or petroleum is synthesized by Fisher-Tropseh reaction in the mid-crust. The current issues, such as gas rush eruption in the coal mines, forest fire, greenhouse gas （CO2） and so on, might be connected with the earth outgas.
