摘要: 近年来世界 各地的勘探实践表明,古老地台活动边缘的推覆体前缘逆冲带不但是最大的沉积区,而且是最大的油气聚集区。在古老地台边缘带最令人感兴趣的是被改造的碰撞型被动边缘,全球最重要的含油气盆地均分布在这里,42%的油气田发现于碰撞地台-褶皱盆地区。岩石圈板块边缘带在地球动力学营力的作用下,不但为沉积岩中所含的有机质向烃类的演化提供了热能,而且在水平挤压力的作用下,使岩石产生密集的裂缝形成次生储集层。控制着板块活动的大断裂是油气运移的通道,在断裂交汇处,巨大的压力降使流体的流动性提高,岩石圈板块的碰撞带,一方面促进了有机质的演化,另一方面使已形成的油气藏重新分配,从而最终导致次生大油气田的形成。

Abstract: Abstract:The article treats the problem of paragenetic relationship between mobile and seismic belts and gas-bearing deposits of the world.Such a comprehensive approach has been never used in geological practice, and we are the first apply it to resolve the problem. The result of re-search represents a substantial advance in understanding of the global regularities of spacial distribution of the world hydrocarbon reserves. Mo-bile and seismic belts are the "indicator" structures controlling the major oil and gas bearing provinces of the world. The authors hope that thearticle will be of interest to broad scientific readership.

Key words: the world, oil-gas distribution, paleo-platform, plate boundary
