摘　　要：在火成岩发育的烃源层中 ,火山矿物橄榄石的蛇纹石化产生大量的氢气和甲烷 ,它们参与了烃源岩有机质的生烃演化过程 ,加大和加速其生烃排量。火成岩在低温热液下蚀变形成的沸石、绿泥石和方解石等矿物对其周围的烃源岩的生烃有显著的催化作用 ,能够促使烃源岩低熟和早期生烃 ;其中沸石的催化活性最为显著 ,绿泥石和碳酸盐在烃源岩中的含量一般较低 。In the hydrocarbon source strata developed with igneous rocks, a large amount of H 2 and CH 4 is generated from serpentinized olivine of the volcanic minerals, which took part in the hydrocarbon?generating evolution process of the organic matter in the source rocks and made more hydrocarbons. Minerals of zeolite, chlorite and calcite etc. formed by the alteration of igneous rocks in hot liquid with low temperature had a significant catalysis on the hydrocarbon generation in the source rocks around them, and made the source rocks low?level mature and hydrocarbon generation earlier, in which the catalytic activity of zeolite is the most notable, the content of chlorite and carbonate in the source rocks is often low with relatively low catalytic activity.
