摘要
与中国东部陆相盆地相比,准噶尔盆地具有独特的石油地质特征。其盆地演化与烃源岩时空展布特点、构造发育特征及异常高压与油气运聚模式决定了该盆地大油气田的油藏类型主要为地层油气藏,其次为背斜油气藏;同时也决定了大油气田的形成和时空展布,地层油气藏主要发育于盆缘和古隆起边缘,背斜油气藏主要发育于南部山前带。该盆地油气资源丰富,勘探程度低,正处于储量增长的高峰期和大型、特大型油气田的发现阶段。
In comparison with the eastern continental basins in China, Junggar Basin has the special characteristics in petroleum geology. Its trait of basin evolution and space-time distribution of hydrocarbon source rock, tectonic development characteristics and oil gas migration-accumulation modes decide the fact that the main type of the large oilfields is the stratigraphie oil gas reservoir and that of the anticline oil-gas reservoir is secondary, which determines the development and space-time distribution of the large oilfields. This basin has abundant oil and gas resource with lower exploration degree and the fast increasing reserves. It is also in the discovery stage of the large and outsize oilfields.
