摘要
结合众多实例，总结了国内外含油气盆地中岩浆活动对油气藏形成条件的影响。一方面，岩浆活动所携带的高热流可以提高古地温，加速生油岩的演化，亦将使与岩浆岩毗邻的生油岩达到高成熟或过成熟，岩浆岩及其围岩蚀变带可以成为良好的储层，岩浆活动还可形成一些特殊类型的圈闭；另一方面，若岩浆活动时间与油气生成、运移与聚集时间不匹配。
Based on lots of examples,this paper summarizes the influence of the magma activity on conditions forming oil and gas pools in hydrocarbonic basins.The high thermal fluid which were brought by the magma activity could increase the ancient geothermal gradient,and accelerate the evoluation history of source rocks.However,the maturity of source rocks surrounding the magma would be very high or over.The magma rocks and their surrounding alteration zones could become good reservoirs.The magma activity could also create some especial traps.On the other hand,if the time of the magma activity doesnt match with the period of migration and accumulation of oil and gas,oil and gas pools would be destroied very largely.
