摘要
以地质、地球物理资料综合分析为基础,从含油气盆地的展布和盆地构造特征等方面探讨鸭绿江断裂带与含油气盆地形成、分布的内在联系。研究表明,鸭绿江断裂带控制的各盆地内存在广泛的湖相沉积与火山活动沿断裂带交替发生的现象。鸭绿江断裂带西南段盆地类型主要为断陷型盆地,东北段主要为断坳叠合型盆地。沿鸭绿江断裂带自西南向东北,盆地形成时代由老变新,盆地内部次级断裂活动程度逐渐减弱。受断裂带活动强弱的影响,西南段盆地具有更好的勘探前景。
On the basis of geological and geophysical data, the study on the internal relations of the Yalu River fault with the formation and distribution of petroliferous basins, was made which involves structural characteristics and spreading regularity. The results indicate that the wide lacustrine deposits and volcanic activities were alternative in these basins, which controlled by the Yalu River fault. The basins in southwestern part of Yalu River fault were mainly faulted basins while the northeastern are fault-depression basins. From southwest to northeast along the Yalu River fault, the formation ages of basins changed from older to younger, and the active intensities of the seeondary faults became gradually weaken. Influenced by the fault active intensity, the basins in southwestern part has better exploration prospects.
