松辽盆地是一中生代形成的伸展裂陷盆地。该盆地中生代地层中含有丰富的石油和煤炭资源。燕山运动期，构造变动、火山活动、古气候阶跃、缺氧事件等充实于盆地演化发展的各个阶段，这些地质事件在盆地演化发展中表现出多旋回特点。地质事件节律的规律性和随机性的辩证统一，控制着盆地生油、气系统的生、储、盖、运、圈、保等诸要素在时空上的有机匹配。研究地质事件节律性变化与油气生、储、盖等之间的关系，对指导盆地油气勘探具有十分重要的意义
Songliao Basin is a Mesozoic extending rift basin. The Mesozoic strata in the basin are rich in oil and coal resources. Yanshanian movement period, tectonic movement, volcanic activity, paleoclimate step and anoxic event are all enriched in various stages of basin evolution and development. These geological events show multi-cycle characteristics in evolution and development of the basin. The dialectical unity of the regularity and randomness of the geological event rhythm controls the organic matching of the various elements in the oil and gas system of the basin such as origin, storage, cover, transport, circle and insurance in time and space. Studying the relationship between the rhythmic changes of geological events and hydrocarbon generation, storage, and cover is of great significance to oil and gas exploration in the basin
