摘要
东西伯利亚盆地是世界上最古老的含油气盆地之一,其南部油气田是中俄油气管道主要油气源区,为进一步落实该地区的油气资源潜力,在区域地质背景和油气地质特征基础上,分析了该地区的油气分布特征及主控因素。该地区油气的分布与大型隆起构造有关,生储盖组合主要受盆地早期的构造沉积演化控制,有利储层的发育与古地形、古沉积环境有关,油气的聚集与受盆地多期构造运动有关。盆地具有巨大的油气勘探潜力,构造隆起斜坡区是未来勘探的重点区域。
The Eastern Siberia Basin is one of the oldest petroliferous basins in the world. Oil and gas fields in the south part of basin are the main oil and gas source areas for Sino-Russian crude oil pipelines and natural gas pipelines. In order to further implement the oil and gas resources potential in the region,based on the regional geological background and oil and gas geological characteristics,the distribution characteristics and main controlling factors of the oil and gas in the region were analyzed. The distribution of oil and gas in this area is related to the large uplift structure. The source rock-reservoir-cover combination is mainly controlled by the early tectonic-sedimentary evolution of the basin. The development of favorable reservoirs is related to the paleotopography and paleo-sedimentary environment. The accumulation of oil and gas is related to the multi-stage tectonic movement of the basin. The basin has great potential for oil and gas exploration,and the tectonic uplift slope area is the key area for future exploration.
