摘要： 准噶尔盆地为典型的中央地块型复合叠加盆地,多旋回的构造形成多样的构造组合和沉积体系,控制着泊气的生成、运移和聚集,有机地化研究表明,盆地发育 6 套经源岩,主要 源岩为二叠系,次为中、下保罗统,油气沿断层垂向运移十分显著。大多数油气藏的形成与油气垂 向运移相关 准噶尔盆地大油气田形成条件和分布规律表明。充足的泊气资源、良好的圈闭条件、 有利的油气运移指向、畅通的运移通道、稳定的保存环境和有效的盖层、优质的储层体是形成大油气田的重要地质因素，缺一不可。预测陆南斜坡带、西北缘斜坡带、阜东斜坡带及玛湖背斜、达巴松凸起等拗中隆起带和盆地南缘为形成大油气田的有利区带。

Abstract: Junggar basin is a typical central massif type composite superposition basin, in which multiple cycle structu re formed various structure combination and sedi-mentary system and controlled oil and gas generation, migrat ion and accumulation. The studies on orga nic geochemist ry showed that there are sixsts of oil source rocks wit hin the basin, majorone is in Permian, the next in Middle and Lower Jurassic. Verticle mi-gration of oil and gas along fatjlts is rema rkable and formation of most reservoirs is related with this fact. Formed cond itions and distribution regulars of large oilfields indicated that sufficient oil and gas resou rces, better traps, favourable oil and gas migration direction, unim peded migration pathway, stable preser vation environment, effective caprock, and high quality reservoir bod y are importa nt geological factors, not a single. one can be omitted. It is forecasted that favourable area are Lunan slope zone, northwest margin slopem，Fudong slope zone, Mahuanticline, Da basong arch and south margin of Junggar basin.
