| 中文摘要: |
| 南亚地区经历冈瓦纳陆内裂谷、冈瓦纳裂解与板块漂移及印度板块与欧亚板块的陆-陆碰撞复杂的构造演化，最终形成了以被动大陆边缘盆地为主的，包括克拉通盆地和俯冲-碰撞带盆地在内的3类沉积盆地，其中被动大陆边缘盆地分布广泛，形成了南亚地区的一个主要盆地群。本文通过对南亚盆地生、储、盖等石油地质条件分析，研究不同盆地类型的油气成藏特征。根据盆地的剩余可采储量和远景资源量对南亚地区的资源潜力进行分析，认为被动大陆边缘盆地油气资源潜力最大，并优选出奎师那-哥达瓦里盆地、孟买盆地和科弗里盆地3个有利盆地。 |
| 英文摘要: |
| South Asia underwent three stages including Gondwana intercontinental rifting, Gondwana cracking and plates drifting and the collision between Indian plate and Eurasian plate, and formed three types of basin that is passive continental margin basin, subduction-collision zone basin and cratonic basin. The passive continental margin basin is widely distributed, forming a major basin group in the region. The characteristics of hydrocarbon accumulation in different basin types are studied through the analysis of petroleum geological conditions such as the source, reservoir and seal. According to the remaining recoverable reserves and prospective resource in basin, analyze the resource potential of sedimentary basins in the South Asia. It is believed that the oil and gas resources in the passive continental marginal basin have the greatest potential, and the Krishna-Godavari Basin, Bombay Basin and Cauvery Basin are optimized as favorable ones for hydrocarbon exploration in the South Asia. |
