近 2 0年来 ,对地壳中热水流体地质作用的研究已渗透到地学研究的各个领域 ,并且是一个经久不衰的研究课题。与现代海底热水流体或大陆热泉活动有关的热液石油的生成问题已引起油气地质学界的普遍关注。热液石油是热水流体与烃源岩发生水岩反应的产物 ,并能与热水流体一起运移。研究热液石油生成和运移的机制有助于了解地质历史中油气的生成与成藏过程。热液石油生成的温度范围从 60℃到大于 40 0℃ ,高温区明显高于传统的石油窗温度 ;热液石油生成过程所需的时间短 ;热液油气运移的通道与热水流体相同 ,这就是断裂构造。据此可以认为 ,在更深的地层圈闭中 ,尤其是产于深大断裂构造附近的圈闭中 ,有更大的油气勘探远景。

The paper briefly introduces the characteristics, expulsion and migration of hydrothermal petroleum in submarine and continental hydrothermal system. The forming temperature of hydrothermal petroleum is from 60℃ to over 400℃,which is higher than conventional oil windows. The formation of hydrothermal petroleum has close relationship with interaction between hydrothermal fluids and source rocks. In hydrothermal fluids, there is high abundance hydrogen, which will react hydrogenation with organic matter in.
