摘要
通过对吉林的区域地质特征分析,认为区域构造运动控制了外围盆地的形成及演化,外围盆地经历了古生代海相沉积和中、新生代陆相沉积,为多类型的叠合盆地。综合分析外围盆地的基本石油地质条件,揭示吉林外围盆地存在古生代海相碳酸盐岩和中、新生代陆相两大油气勘探领域,具有广阔的勘探前景。进一步明确吉林外围盆地的勘探方向,坚持海相和陆相勘探并举,古生代与中、新生代兼探。
Regional geological features of Jilin peripheral basins are analyzed, it is inferred that the development and evolution of the peripheral basins are controlled by regional structural movement. Multiple peripheral basins have become multi-type superimposed basins after experiencing Paleozoic marine deposition and Meso-Cenozoic continental deposition. The basic petroleum geological conditions of peripheral basins are analyzed systematically. Two big oil and gas exploration fields are found in the basins, i.e. the Paleozoic marine carbonate exploration field and the Meso-Cenozoic continental exploration field, both of which have broad prospect for exploration. It is clear that both marine and continental exploration, both Paleozoic and Meso-Cenozoic exploration should be laid the same emphasis.
