基本要素包括一套烃源岩、储集层、盖层和上覆岩层，作用是圈闭的形成和油气的生成—运移—聚集。
The essential elements are source rock, reservoir rock, seal rock and overburden rock, and the processes include trap formation and the generation-migration-accumulation of petroleum.
多期次的构造运动和适度的变形，为油气运移、聚集和圈闭的形成打下了良好的基础。
Owing to tectonic activity with multiple stages and appropriate deformation, it lays a good foundation for hydrocarbon migration, accumulation and trap forming.
它加速了生油岩的成熟过程，形成新的背斜和断层圈闭构造，而且还控制了新生代油气的运移和聚集。
It accelerated the hydrocarbon maturation process, formed many new anticline and fault traps, and controlled Cenozoic hydrocarbon migration and accumulation.
研究结果认为：2号和3号圈闭裂缝最发育，是齐家古潜山的最有利油气聚集区；
The result of research is that fractures are most developed in trap 2 and 3, where the most favorable hydrocarbon accumulations in Qijia buried hill are located;
