四川盆地北部盆地受控于周边多个造山带的多期活动,区内多组构造叠加与复合,纵向上发育了多套有利的生储盖组合。研究区输导体系可以分为断层型、储层型、裂隙型及不整合面型4种。针对四川盆地北部川西北和川东北地区地质特点及研究区油气成藏模式,分析影响研究区油气成藏的主要因素为：首先是古隆起控制油气的分布,其次是隐伏断裂在纵向上的沟通为油气的输导提供了条件,再次之是前陆盆地中油气的分布受储层发育的控制,最后是晚期构造的叠加使得油气进行二次调整成藏。

Northern part in Sichuan basin was controlled by multistage actions of surrounding orogenic-zones which result in many superpositions and recombinations of structure and multiple favorable sources- reservoir-cap combinations in vertical direction.The migration transporting systems in the research area was classified into four kinds：fault form,reservoir form,fracture form,and unconformity plane form.According to oil-gas accumulation characteristic of northwest and northeast area of Sichuan Basin,controlling factors of oil-gas accumulation are following as：（1） the paleo-liftes which controlled the distribution of oil and gas;（2） communication of insidious fault in vertical direction which provided a favorable condition for oil-gas migration and accumulation;（3） reservoir developments which controlled the distribution of oil and gas in the foreland basin;（4） the structural overlay action in later period which accelerated the hydrocarbon reservoir′s evolution.
