摘　　要：俄罗斯西西伯利亚盆地为中-新生代超巨型克拉通盆地,油气资源丰,是世界最大的含油气盆地。运用层序地层学方法,在分析构造、沉积演化过程的基础上,将西西伯利亚盆地划分为3个含油气系统。通过综合分析含油气系统的烃源岩、储集层和圈闭类型等要素,认为巴热诺夫-纽康姆含油气系统主要为上侏罗统-森诺曼阶的常规油气藏和巴热诺夫组的自生自储式非常规油气藏;托尔古-秋明含油气系统主要为中-下侏罗统秋明组的常规油气藏和基底顶部风化壳油气藏;West Siberian Basin is a Mesozoic-Cenozoic giant cratonic basin, which possesses abundant oil and gas resources and can be regarded as the largest petroleum basin in the world. By using sequence stratigraphy method and on the bases of analyzing the course of tectono-sedimentary evolution, the basin is divided into 3 petroleum sys- tems. The comprehensive analyses of the source rocks, reservoirs, traps and other factors in each system show that Bazhenov-Neoeomian petroleum system is composed of a conventional petroleum reservoirs in Jurassic-Cenomanian Stage and self-sourced and self-preserved unconventional petroleum reservoirs in Bazhenov Formation; Togur-Tyu- men petroleum system forms a conventional petroleum reservoirs in the Lower-Middle Jurassic Tyumen Formations and the weathered crust petroleum reservoirs on the top of the basement; the Northern Mesozoic composite petrole- um system generates the gas reservoirs in Pokur Formation of Aptian-Cenomanian Stage and condensate reservoirs in Jurassic-Neocomian Stage.
