摘要: 酒西盆地位于青藏高原的东北缘,天然地震活跃,喜马拉雅运动在盆地的活动可划分出11个阶段,其构造挤压强度依次由弱变强,在上新世中期达到高峰,是该区构造的主要变形期和定格期,也是该区油气成藏的主要时期。盆地的构造变形从渐新世开始发育,沉积中心不断北移,各构造带的发育时间从南往北依次由早变晚,控制了该区断层相关褶皱、构造圈闭及其油气藏的带状分布规律。天然地震对油气的运聚成藏有重要影响。

Abstract: Jiuxi basin is located in the northeastern margin of Qinghai-Tibet plateau with active natural earthquake. Himalayan movement in this basin can be divided into eleven stages in terms of weak-strong intensity of structural compression. The Middle Pliocene is its main deformation/formation stage and petroleum accumulation stage in this area. The structural deformation originates in Oligocene. With cont inuous north-shifting of sedimentary center, the development periods of each structural belts tend to postponing from the south to the north, thus controlling the fault- related fold, structural trap and zonal distribution pattern of oil-gas reservoirs in this area. It is indicated that the natural earthquake is an important role in petroleum migration and accumulation.

Key words: Jiuxi basin, Himalayan movement, natural earthquake, petroleum accumulation
